Instead of using @color/background directly, use ?attr/colorSurface
so that changes can be made to the theming easier. This also
resolves some more minor issues regarding certain widget's
backgrounds.
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
Both improve and use dialogs
- The AlertDialog style now properly colors dialogs with the primary coler
- The accent & blacklist dialogs are now based on AlertDialog for their buttons, reducing layout complexity
Completely refactor the blacklist dialog to not only use the Storage Access Framework, but also to completely eliminate the material dialogs dependency.
