Dev dashboard disable

See issue #99

Changes:
* Deleted games don't show on load/deletion
* Disabled games do not have the disable button
* Table entries have proper html/css when games are disabled

Issues:
* ~~Queue position does not update when a game is deleted or disabled. Is there a way to reload the page builder? Or should I manually go through and get the queue positions?~~
* I have hardcoded the gettext("Disabled") in `developer_dashboard.js` line#72 when it should really match the `statusName` filter from `helpers.js`. How would I call this function? I can't seem to figure that out.
* Waiting time does not update when a game has been put out of pending and back into pending state. Blocked cvan/galaxy-api#194.
