Revamp Projects with new navigation

Summary:
A refresh of Projects including a new navigations UI.

 - New Navigation UI.
 - Auto switch default page if Workboard has been initialized
 - Move Feed to it's own page
 - Increase 'tasks' on Project Home to 50 over 10
 - Fix various display bugs on Workboards
 - Remove 'crumbs' from Project portal (unneeded).

Test Plan:
- clicked a link for a project with no workboard and saw the profile
- clicked a link for a project with a workboard and saw the workboard
- navigated around the various edit pages, inspecting links and making sure things linked back to the new profile uri
