Struct. for edit/delete streams. Not working yet!

* Need to get Marvin to support additional features before can proceed with this.
* Missing in Marvin: list all streams for logged in user, publish/unpublish/delete stream, delete single entry in stream
Further progr. on stream list/publish/unpublish/del

Listing of user streams is working mostly correctly. Still missing some required fields (movie name, stream status). A lot of testing todo...
More specifix CSS-rule for loading

* Otherwise causes problems elsewhere (your_streams.html)
Play button implemented, still missing some funct.
Small styling fix to loading spinner
Workaround fix for deleting streams

Marvin isn't cascading the stream entry deletions properly, so need to "manually" delete the stream entries before deleting the stream.
Fix for the stream deletion workaround
Stream editing working, still stuff to fix..

TODO
* Missing the movie information (must be fixed in Marvin first)
* Test/Ensure that jumping in playback works as expected
Merge branch 'streamEditing'
