Subject: [PATCH] Implement user dashboard view

This changes the way the change list view is layed out (flexbox
instead of tables) for a couple reasons:

+ Table elements (td, tr, etc.) cannot be arbitrarily appended
  to just any DOM node, which caused breakage when I originally
  attempted to use a <content> tag to bring in the header or
  group title content into gr-change-list-item.
+ The flexibility of flexbox allows us to style the change list
  much easier on smaller screens, so it was probably going to
  happen anyway.
+ Full-width (colspan="<total number of columns in the table>")
  rows for the headers is much more difficult when using elements
  outside of the gr-change-list-item brought in via <content> as
  described above.
+ gr-change-list-item was doing too much anyway.

Feature: Issue 3700
