Summary: Reworks Maniphest into a two column view. Moves priority and color to header, assignee to sidebar. quest points to header, and author to gutter. may be some confusion since priority only displays on open tickets.

Test Plan: with and without description, custom fields, points, tablet, mobile and desktop.
