Different highlights for 'active' vs 'inactive' project states in the view

[wlingke]

1. All project models should have a project.data.active = true or false. False if project was created 15 days ago or more. Calculate this for now on the client side. I am investigating if I should do this on the server side Nightly task runner that marks active/inactive state on projects #3 instead.

The state should be set in the angular model constructor /static/client/projects/models/Project.js at data.active

2. Create different CSS highlighting on the "My Projects" page for active vs in not active projects.

Feel free to close this once you're all set with 2). though I imagine it'll be apart of #1
