[Matrix] First alpha with beta api

First alpha using the new beta api. Highly experimental, no warranties!!

For Kodi Matrix only right now.

Install and re-enter your login credentials. Note that you now have to use your crunchyroll email address, not the username.
When starting and having entered the login credentials, it still might show "You need to be logged in" - select that and confirm, it should progress.

Right now only the playlist is working, but without markings for seen episodes or paused episodes - those cannot be resumed right now.

!!! Please use at your own risk, this is purely for demonstration purposes and for testing things.
