Lots of work on sign up screens, including attributed labels!

Holy shit, how did I not know Xcode now lets you create attributed strings in a storyboard/XIB?! This means all the work we did to implement the Slash library for Allan's app is mostly obsolete.
Sign up screens are pretty far along. Main outstanding issue is implementing text fields.
Sign in screen is also nearly done.
