Merge branch 'add_last_push_widget' into 'master'

Add last push widget to starred projects dashboard

This adds the last push widget to the starred projects dashboard. If a user set the starred projects dashboard as their preferred dashboard they would not see last push widget. The look is seamless between starred and 'your projects' dashboards.
