Improve Project list layout

Problem

Feature

• [x] Restrict Project list to User.division unless User is superuser.
• [x] Style Project list like the ARAR progress overview.
• [x] Make Project list filterable by typing on type, title, year/number, team list like current project list.
• [x] Add "Download all Projects as CSV" button.

The new behaviour is as follows and needs test coverage (checklist for tests):

• [ ] Current Project list (admin change_list) shows Projects of all Divisions and was moved to Superuser only "backstage" menu.
• [ ] New "shiny" Project list is filtered to own Division and linked from menu, index, and search bar. Not paginated, but grouped by Program with expandable details.
• [ ] New Project list is a Django ListView and a departure from the overloaded admin site.
• [ ] New Project list does not filter by Team yet. (Extra plumbing required as it's a M2M).
• [ ] Search box in menu searches for partial match in Project title.
• [ ] Projects breadcrumb links to new Project list.
