Added a new feature this week

This week we pushed out a new feature! You can now mark repositories as favorites. This is a great feature for helping speed up initial load and narrow down the number of pull requests shown on the home page.

Before this feature, we would show all open pull requests for all repositories you were a part of. We got plenty of feedback though that it was too much information and that it would take too long to find the most relevant pull requests. With favorites, we expect this problem to be a thing of the past!
