Policy flurry!

I was already excited when Policy 3.7.0 was released, and now we're up to Debian Policy 3.7.2! Admittedly, some of that is the rethinking of the cgi-bin to cgi-lib change which was agreed on years ago but which has since been rethought and has now been retracted, but there have also been a lot of typo fixes, fixes around the X migration, and other good work. Many thanks to Manoj for all his work in this area. It's great to see multiple Policy releases.

lintian has been updated to support 3.7.2 already in Subversion. I was hoping to commit a bunch of the patches and implement a bunch of the wishlist items from the BTS, but I'm not sure if I'm going to have time. I'll probably upload whatever's in Subversion on Friday to not let too much time go by with the new Policy version without a new lintian.
