Added to JIRA under sprint Spaces V: Perms Strike Back.

1. Roles: Organize alphabetically in the UI. 
2. A viewer shouldn’t be able to add a dataset to a space if it doesn’t have the permission. Add the permission check in create space and edit space for datasets and collections. 
3. Login with google and Facebook. 
4. Add Follow/Unfollow button to the spaces
5. Fix the UI for the collections that are being followed. 
6. Fix cases in checkPermission that are vulnerable to None.get calls CATS-75

Spaces–Other Bugs

1. Change color of badges holding the resource counts (on home page, after login). Currently, is same color as the associated resources; red.  But the latter are clickable links, leading user to believe that the badges are clickable too, although they aren't.
2. Create space, should move the expiration radio above the time to live (assuming these go hand in hand).
