Change project search so that it is hitting the right API endpoint so that we are getting more than just the users projects

Change DiffActivity to use a RecyclerView to prevent huge view inflation and out of memory exceptions.

Make it where we do not get multiple projects screens after logging in to a new account. Attempt to add the newly signed in account to the drawer after signing in

Remember the last logged in account and show it initially when the app starts. Also switch to the latest accessed account when the currently active account is signed out.

Change project members fragment to have a footer button so that you can go straight to the associated project group.

More progress on allowing the user to change a project members access level, as well as changing a group members access level
