Admin username with 3 characters not possible

I tried to use rix (for obvious reasons) which would not allow me to set up an admin account.

I will fix on the next commit. If you would like to destory the database and start over, you can edit this line: https://github.com/causefx/Organizr/blob/master/js/user.js#L44

if(username.length<2) { return this.markInvalid(input, "Sorry, user names must be more than 2 letters."); }

Thx, that worked superbly!
