Add the UI and data components for a disc number value within the album
detail view.
This is the first-step of a multi-step addition to finally implement
disc numbers.
Rename LoopMode to RepeatMode, which is generally much clearer
than the previous name.
This changes all non-breaking instances of "loop" in the app with
"repeat".
Completely rework the base adapter class to require less boilerplate
and properly handle cases such as diffing. The major adapters have
been migrated to this system, but the other adapters have not been
changed so far.
This is only part 1 of a multi-part rework, as this is an incredibly
complex system.
Move all fragment instances to the new ViewBindingFragment paradigm,
which should help immensely with reducing memory leaks from list
bindings and to really alleviate the overloaded onCreate functions.
Migrate to a centralized constant table for easier management.
Previously, Auxio would tie constants to the class itself, which
led to a largely disjointed system that relied on an internal table
so that it would stay sane. This commit moves all of those constants
to a single table for easier usage and management.
