Re-add 2x2 widgets. They were originally removed due to strange layouts
in landscape mode, but that has now been fixed with a new "tiny" layout
meant for that specific edge case. Also rename the widget forms to more
sensible names and make the small (previously minimal) widget be
text-only again.
Refactor the way music models are constructed to achieve the following:
- Add a unified interface for resolving display names of artists
- Disambiguate the role of Header in the music objects
- Eliminate the need to load strings in with a context when creating
Header instances
Prevent issues with malformed widget forms on certain devices by
increasing the minimum widget height to 152dp, which is the height
that the minimal widget should take up.
Enhance widgets in a couple of ways:
1. Make the cover art expand to fit it's aspect ratio with padding
instead of the entire widget. This does the cover art justice and
is more visually appealing in general.
2. Add two new widget forms: Terminal, which applies to only the
smallest widgets, and Minimal, which applies to short and wide
widgets
The plans for widgets have changed somewhat. Instead of 4 or so
variants, there will instead be one unified widget that chooses
different layouts depending on its size. The first one added is the
full widget, which shows more controls as long as theres enough
space.
Modify the minimal wdiget so that it can work on Android 11 and below.
Was not actually that hard, mostly changing layouts around all things
considered. This also splits up the default view and the main widget
views, which makes managing UI state much easier.
