Merge SyNtheticNightmar3's 'next' branch

Changes include:
- Regenerate some launcher icons to remove some minor fuzz (minor image reduction size)
- Correct/relocate seekbar/time in 'Now Playing' UI
- Remove an unused lib to clear up build warning

(@Blackburn29, let me know if the android-support-v4 removal is something we don't want to do; I'm able to build fine without it)
