Adjusted C++ code to handle with new and renamed objects, as well as
properties with different types.
As a result of changing types, the QML side had to be updated as well.
I hope I found everything by manually testing.
Additionally, the Qt Quick application has been updated to test the
remote sessions more easily and to make it launch again.
Deduplicated code in the NarrowAlbumCover and WideAlbumCover.
Additionally, this fixes a bug where the NarrowAlbumCover would behave
wrongly with album covers with an aspect ratio not equal to 1.0.
Resolves #22
I reused the AlbumDetailPage for playlists, as both are very similar. If
they end up being too different, I might want to look into splitting
them up, but for now it will do.
* [ui] Added: Blurry previews of images before they are loaded
Also fixes a bug where ApiModel would remove items that already started
with a lowecase letter or didn't start with a letter at all.
