Added a box on the Dashboard page for filtering results.

Issues that still exist:
 - [x] Old listeners never removed.  The page is still listening for resizes from the old boxes, but fails during the resize because the box doesn't exist anymore and throws an error.
     - [ ] This is partially fixed.  Old listeners still aren't removed, but the redrawing is suppressed and doesn't occur unless the monitor is visible.
 - [x] The page refresh brings up all of the boxes, not the filtered ones.
 - [x] The monitors have spaces between them and are not aligned to the previously defined grid.
