Adjustments to work better with SoundCloud
-Turns out we can't queue content from SoundCloud and the other video sites together, a different player is used for audio and video.
-Made it so that it doesn't clear out playlists on stop or 'Play now'
-Added a button to the end of the button group for clearing playlists
-Slight cosmetic adjustments for the new button layout
-Fixed the repeat toggle button so that it updates to the right repeat mode
-Added a 'loading' view for buttons
Added 'Play this Next' function
