Sample playlist generated when no profile at pageload.
I removed notification about playlist not-being-saved from the playlist, and added it to the playlist selector.
Removed renaming and removing buttons from sample-playlist-selector.
Modified the call to loadProfile at pageload, to generate sample playlist if no playlists in profile.
Modified loadProfile to only try to render and activate playlists if there is at least one. Also, removed duplicate access-key setting.
Sample playlist generated when profile loaded without playlists. Also, deletePlaylist waits until removal-animation finishes, and then either activates the first remaining playlist, or generates a sample playlist (if no playlists remained after the removal).
Merge branch 'fake-sample-playlist' into rebuild-profile-management

I re-implemented and modified the sample playlist generation.
It now adds a playlist to the page, but does not create an actual one on the server.
It is added if no profile loaded, if profile loaded without playlists,
 or if a playlist is deleted and no playlists remain on the page.
Also, modified deletePlaylist, to wait <2 * animationSpeed> time for the removal-animation to finish. Then, it either activates the first remaining list,
 or generates a sample one (as mentioned above).
