Add members
Remove 'you are allowed to use this remote.'
Move adding members logic to private method.
Create embedded document with a list of user's memberships.
Modify remote#create and remote#update so it also updates the user's list of memberships.
Refactor so logic is in several smaller methods within appropriate models.
Remove remote owner from remote memberships. Otherwise, the remote owner would have conflicting permissions.
Don't show added members by default.
Add class to add padding to ul.
Add views to list a user's memberships.
Add @memberships variable containing array of all remotes where the user is a member.
Divide remotes and memberships into two columns so they're more easily viewed.
