5.2 changes, part 1

Copy-pased everything in a separate folder to do 5.2 changes so the 5.2
and 5.1 code can live side-by-side until the patch.

All known changes as of 2/23/13 are in, I think. Rearranged some things
in light of the changes (split out T30s into their own table, moved some
checkboxes around, etc.)
Merge remote-tracking branch 'remotes/suz/master'
