* Consolidated main-setttings into a single file
* Debug settings are only enabled in the DEBUG build
* Moved LeakCanary (debug) specific stuff into a small class that's only shipped with the debug build

* Moved the player error logic to separate class specially created for this purpose
- remove duplicated string (name) and avoid potential duplicate (autoplay_never_description -> Never, autoplay_always_description -> Always because they are just "Always" or "Never"). Fixes#4268
- leakCanary string removed (fixes#4233)
- add MediaStyle notifications for Background and Popup playback
- reduce excessive notification updating ( / recreating of Notification.Builder object) when playing background / popup media
- add new buffering state indicator (can be disabled)
- upscale close icon / downscale replay icon
- add notification slot settings
- move notification settings to appearance
- fix Metadata (song title, artist and album art) sometimes not being set correctly
- other misc notification fixes

For all manually-created images PNG have been kept.
- rename all icon attrs to have a `ic_` prefix
- always use `_24dp` icons, because there is no real difference, since they are vector drawables
- always use the original name found on material.io for icon drawables, as to not create confusion and possibly duplicates. Icon names can still be different from real drawable names, though I have made some of them compliant to this or maybe more meaningul.
- remove duplicate `getIconByAttr()` in ThemeHelper (use `resolveResourceIdFromAttr()`
- use standard icons for `expand_more` and `expand_less` instead of triangles
- use `play_button_outline` instead of custom PNG as play button in VideoDetailFragment (questionable, as there is no shadow anymore)
