Take the first step on the long journey of fixing "Projects"

Summary:

• Allow more than the 100 most recent projects to be viewed.
• Provide some useful filters.
• Default the view to your projects, not all projects.
• Put query logic in a query object.
• Put filter view logic in a view object. We can port more stuff to it later.

Test Plan: Looked at active/owned/all projects. Set page size to 5 and paged
through projects.
