Clean Up Google Music [De-Instant Mix/Radio]

Google Music includes auto-generated Instant Mix/Radio Station playlists that cannot be removed. There are also other cards mixed in with the albums such as suggested albums and user playlists. The user should be able to pick and choose which types of cards are displayed. The I'm Feeling Lucky button can also be turned off.

The settings page now includes a set of checkboxes to customize what the user should see. These settings are synced across chrome installations if you are logged into chrome.

There is also a setting to force all the albums to be resized to a uniformly small size instead of being mixed between large and small.
