Create a new playlist when no playlist is loaded

[lidel]

Right now playback controls work only on preloaded playlists. When there is no playlist, there is nothing to control.

It may be a better UX to create a new playlist instead of doing nothing.

• If page is an album or shared playlist start playing the very first item
• if there is no play button, go to 'Home' and start "I'm Feeling Lucky" radio
