lintian 1.23.35

This was the big thing that I felt like I *had* to get done before I went on vacation, and it's done. I was massively behind on lintian bugs, and now I'm mostly caught up and hopefully have killed the worst of the desktop false positives.

There's still a lot to do, and lintian is still over 100 bugs again, but the rest can probably wait.

Debian Policy is of course still a mess, but that's probably not something I'm going to successfully tackle before I disappear on vacation for a bit.
