* Implemented simple Kodi markup code applier for the Now Playing fragment
* Moved to UIUtils; added early exit; now handles nesting of the same type
* Added handlers for LOWERCASE, CAPITALIZE, LIGHT and COLOR
- LOWERCASE and CAPITALIZE work, LIGHT and COLOR are just stripped out
- inlined the TextAppearanceSpan new's. Turns out they can't be reused.
* updated javadoc
* fixed crash when capitalizing an empty word
