Use Google Music from inside Jukebox

[mmilkin]

What

Using gmusicapi Jukebox now supports the use of GoogleMusic accounts.

Adding a new GooglePlayStorage('username', 'password')

What is still to do:
Add MultipleStorage to access multiple users accounts as well as local accounts.
Have a smarter Authentication layer when the session expires.

This is making all kinds of blocking calls in the event loop.

[mmilkin]

[mmilkin]

Made some changes still need to fix tests and add get_uri that returns a differed but a good start .

[mmilkin]

this is the bad.

[mmilkin]

Now with less blocking.
