Implementing profile updating form profile package.

Profile saving works.
Fixed the bug of not setting CSRF cookie by decorating index view with ensure_csrf_cookie
Another bug fixed: records' provider ids were not correctly rendered, due to a typo in renderPlaylist.

When currently played video ends, a universal play next video function is triggered. It decides what to do, based on whether the current video is in a playlist and whether there is a following video in the playlist. Of course, this function also supports extension of the app with additional providers.
