Prototype Repo list added. Does not properly support switching between multiple github accounts at the moment (all are adding to the same repo list in the current version).
Deleting saved repos when deleting user account/ storing separate lists for each user should now be working. Changed login code so that it doesn't care about upper/lower case (since github doesn't). Specifically I set it so we always convert input from the username field to lowercase (so we don't have to do toLowercase() comparisons everywhere else).
