remove unused submodule

This ocmmit adds a LiveTvChannels page for displaying the programs that
are now playing.

The section Live TV Channels on the main page now shows the TV channel
list in order of the channel number.

Additionally, it fixes an issue in ApiModel, where it would not reload
when a new loader was assigned. This is now fixed and some code on pages
that worked around this fix has been removed.

+\page contributing Contributing
+\brief All resources for (potential) contributors
+
+This page should contain all resources for people who'd like to contribute to the project. 
+If that happens to be you, thank you for considering to contribute to this project! 
+This page will describe how the process goes, what code style this project uses and more useful information.
+
+# Development process
+Development happens at [GitHub](https://github.com/heartfin/harbour-sailfin). 
+Currently, both the library Jellyfin-Qt and the [Sailfish OS](https://sailfishos.org) app named Sailfin are developed in the same repository.
+
+## Create or find an issue to work on
+If you want to contribute code, please check if an issue exists. 
+Otherwise, create an issue describing what feature you'd like to develop before creating a merge request.
+
+## Start working on your code
+Clone the git repo and create a new branch. 
+If you have commit access to the repository, please create a branch in the form of `<issue-number>-<issue-title>`. 
+For example, `36-control-remote-jellyfin-sessions`.
+
+Now you can start writing your code and create commits. 
+Please create focussed commits, that is, do not commit anything not related to the issue you are working on.
+Also state what you're changing in the commit message and add an entry in the file `rpm/harbour-sailfin.changes`.
+
+If this is your first time contributing to the project, don't be shy and feel free to add your name to the contributors list in `sailfish/qml/pages/AboutPage.qml`!
+
+## Submit a merge request
+Now that you have finalised your commit, you can create a merge request on the repository.
+Make sure that you have followed the contribution guidelines on this page.
+Someone will review it and if all is good, they will merge it in.
+
+Congratulations on your contribution!
+
+# Code style guidelines
+The code should follow the [Sailfish OS Code Conventions](https://docs.sailfishos.org/Develop/Apps/Coding_Conventions/) with the following exceptions:
+
+## Exceptions for C++
+- Put curly braces on the same line as the declaration, example:
+  ```cpp
+  int foo() {
+      // implementation
+  }
+  ```
+  instead of
+  ```cpp
+  int foo()
+  {
+     // implementation
+  }
+  ```
+  Rationale: I hate pressing enter and am used to the former. Moreover, it is already all over the place. Bad rationale, I know.
+
+- Close namespace brackets with a comment in the form `// NS Jellyfin`, example:
+  ```cpp
+  namespace Jellyfin {
+  namespace Nested {
+      // Content
+  } // NS Nested
+  } // NS Jellyfin
+  ```
+  Rationale: Easy to know what namespace the bracket closes, since namespaces tend to span over large portions of a file.
+
+- Use include guards in the form of `NAMESPACE_CLASSNAME_H`. Example:
+  ```cpp
+  #ifndef JELLYFIN_MODEL_USER_H
+  #define JELLYFIN_MODEL_USER_H
+  namespace Jellyfin {
+  namespace Model {
+
+  class User {
+      // Methods etc
+  };
+
+  } // NS Model
+  } // NS Jellyfin
+  ```

+\page guide-getting-started Getting Started
+\brief Installation procedure and first application using this library
+
+This is a tutorial on how to use Jellyfin Qt library.
+
+## Project setup
+
+The library works as [a QML plugin](https://doc.qt.io/archives/qt-5.6/qqmlextensionplugin.html). 
+Compile the library, install it in the QML plugin path and add a qmldir file like this:
+
+```
+module nl.netsoj.chris.Jellyfin
+plugin JellyfinQt
+```
+
+You should then be able to import it in your QML files.
+
+
+```qml
+import nl.netsoj.chris.Jellyfin
+```
+
+\note
+In the documentation, the URI nl.netsoj.chris.Jellyfin will be used. 
+If you deviate from this, make sure to put the plugin in the correct location,
+as well as using the correct import statements in QML.
+
+## Hello Jellyfin!
+
+The first step for interacting with the library is setting up an \ref Jellyfin::ApiClient. 
+This object handles authentication. 
+
+
+
+\warning
+The way authentication works using ApiClient will change before the next major release to support multiple accounts! See \issue{4}
+
+Lets create an instance of ApiClient that is reachable from everywhere, by putting it in the ApplicationWindow:
+
+```qml
+import nl.netsoj.chris.Jellyfin as JF
+import QtQuick 2.0 as QQ
+
+QQ.ApplicationWindow {
+    readonly property JF.ApiClient apiClient: _apiClient
+
+    JF.ApiClient {
+        id: _apiClient
+        appName: "The name of your client"
+    }
+}
+```
+
+\note
+As an alternative, you could create a QML file only containing the ApiClient and [declaring it as a Singleton](https://doc.qt.io/archives/qt-5.6/qtqml-modules-qmldir.html#contents-of-a-module-definition-qmldir-file)
+
+## Authentication
+If the user already has logged in and the credentials are stored, this is quite easy: 
+the \ref Jellyfin::ApiClient::authenticated "authenticated" property will change to true and the corresponding signal will fire.
+You don't have to do anything else!
+
+When the user never has logged in, the signal \ref Jellyfin::ApiClient::setupRequired "setupRequired()" will be fired.
+When this happens, you should let the user enter a server URL and set it as the \ref Jellyfin::ApiClient::baseUrl "baseUrl" property.
+You can get a list model of servers in the local network using the \ref Jellyfin::ServerDiscoveryModel.
+
+After the \ref Jellyfin::ApiClient::baseUrl "baseUrl" property has been set, the slot \ref Jellyfin::ApiClient::authenticate "authenticate" should be called with an username and password.
+When authentication was successful, the property \ref Jellyfin::ApiClient::authenticated "authenticated" will be changed to true. 
+Otherwise, the signal \ref Jellyfin::ApiClient::authenticationError "authenticationError" will be fired.
+
+\note
+To show a list of available users, one can use the \ref Jellyfin::ViewModel::UserModel "UserModel" and \ref Jellyfin::ViewModel::PublicUsersLoader "PublicUsersLoader".
+However, this requires knowledge of the Loader and Model system, which will be explained in the next chapter \ref guide-apimodel-loader
+

+\brief All guides intended for developers working with this library.
+
+All guides assume familiarity with QML. If you aren't, [the free online QML book](https://www.qt.io/product/qt6/qml-book) is a great place to start.
+Note that this book is written for Qt 6 QML, while this project is using Qt 5 QML.
