Add a 'create' policy to Project

Summary: UX on this could probably be better 'disabled' crumbs don't appear to have any visible difference, and the policy error has to load the /create page rather than being a modal - not sure on the way to fix these.

Test Plan: Tried to create a project with and without access, saw suitable error.

Make the policy control a JS dropdown with icons

Summary: Ref T603. After thinking about this for a bit I can't really come up with anything better than what Facebook does, so I'm going to implement something similar for choosing custom policies. To start with, swap this over to a JS-driven dropdown.

Summary:
Dropdowns have some `span` rules and such currently. Give them class-based rules instead.
