Change the login and session info to the username #9
Description
Right now, the login page requires the user's e-mail and then that e-mail is stored in the session. In the effort to make things even more secure (so people don't have to keep entering their e-mail), this should ideally be changed to using the username as the login (and in the session). The proper bcrypt and PSQL authentication is still necessary...it just will use the username instead of the e-mail.
