Refactored MusicListFragment and PVRListFragment to use AbstractTabsFragment
Fixed scrolling in a nested scroll view using espresso
Fixed issue with setting and checking Kodi major version
* Allow the RemoteActivity and BaseMediaActivity to show a volume controller dialog when hardware volume keys are pressed
** The dialog handles the key events and makes callbacks to the activities to handle showing the dialog itself
* Minor improvements
** Make HighlightButton render in the IDE GUI Editor
** Minor code cleanup
** set currentActivePlayerId = -1; on playerOnStop in BaseMediaActivity to be more consistent
