Add filters to nav bar

Filters between qa cr and gtg
Complete makeover of pull dash's front end

Removed purecss and replaced it with bootstrap. Everything is now responsive.
Added filters for qa cr and good to go. The auth page can now be submitted with
the enter key.
Jquery has been added as well. Good times for everyone.
Happy Code reviewing.
