On startup, the DeviceProfile would not be serialized properly to a false
assumption that QJsonValue.toString() returns the JSON representation of
the given value. This now has been fixed by creating a QJsonDocument
converting it to a string.
There were some constructors in the DTOs which allowed construction of
DTO which weren't fully initialized. These constructors have been made
private, as they are still used in the 'fromJson' methods. Additionally,
a constructor with all required parameters to fully initialize the
class has been added.
Additionally, the Loader class has been modified, since it no longer can
assume it is able to default construct the parameter type. The parameter
is now stored as an optional.
Closes #15
* Show the now playing cover when playing an item, otherwise show the
collection cover.
* ItemModelLoaders now correctly expose list properties of non-built-in
Qt objects
* toString is now implemented for lists, fixing some query
construction code.
* PlaybackManager now clears the playlist when playing a single item to
prevent weird behaviour.
* The covers are slightly updated.
ApiClient was refractored to use PIMPL. This is mainly done to reduce
compile times whenever the implementation of ApiClient itself changes,
since a lot of files include it.
The loaders have gained support for body parameters, this was somehow
omitted before.
* Properly keep track of the current offset and total recourd count in
models.
* Catch exceptions and store them in errorString properties wherever
applicable in loaders.
Loading logic should be extracted from the model, to make
loading the data from other sources, such as a local database for
synchronised items, possible.
