Changed to three column layout #96

Changing the markup coming out wasn't so bad, but updating css and js got obnoxious.

Had to update my status fetching ajax calls a bit.  What I was doing was a fetch per status bucket.  ie fetch all 'status: needs qa' and all 'status: fixed'.  Store all the github ids that had that label and display that status.

Two problems.  One, I was assuming every ticket would get 'status: fixed' and that any that didn't were dev errors.  That wasn't a helpful assumption.  Two was worse.  I forgot that each search query only gives me open tickets.  I'd need a second one to get all closed tickets for that status.

Getting all those closed tickets was extremely slow.  Slow enough that it wasn't reliable that I'd have a network connection the whole time.  Instead of getting them all at once or even per status, I queried for them per milestone.  Seems speedy and it will give us exactly one extra api call per milestone page.
