Redesign the loading UI to be in line with the rest of Auxio and the
upcoming Android 12 splash screen [sort of]. This also updates the
header and button designs so that the layout heirarchy is better/more
information dense.
Do two things to the margin and padding system:
- Remove the redundant padding/margin dimens and replace it with a unified "spacing" dimen namespace
- Make most margin and padding dimens follow the divisible-by-8 rule in material design
Fix two more fast scrolling issues:
- Fixed size of the view would cut off larger fonts
- Thumb would briefly show when the view would initially start
This custom view was a mistake, but anything for less kbs.
