Users feature

I added the monban and monban-generator gem to manage user login, i tweaked it to allow for username and email as user keys, and created a route back to the login page until we have a homepage to route it to, so I can test it's validity. I also removed some password reset files and folders that came with monban, since we do not need them, and further removed some tmp files that appeared and were unnecessary
Why has this been removed?
