(style.css) Darken font color of body text
(partials/arch) Add ARCH contract details & electronic signature forms
(AppCtrl) Set profile info if 'pid' property is null on login

This is a quick hack that will allow us to preload data for students (like
whether they're an ARCH student or not), while still allowing their official
profile information (only fname & lname at the moment) to be set from LDAPS
after they login for the first time.
(rules.json) Add schema and rules for ARCH
(ARCH) Add project listing page and contract functionality
