rxvt-unicode Matcher Patch for Bug Numbers

A while ago Ganneff wondered weather it would be possible to make the matcher extension of rxvt-unicode also pick up something like #12345 and turn it into a link into the BTS.

It isn't—or rather, it wasn't. The idea got stuck in my head and invested some time to make it happen. Here is the quick'n'dirty diff to make it happen:

The diff is intentionally small so it is clear what is happening here. And it should give ideas for other extensions that one would like to make. I don't consider it though flexible enough to submit it upstream. Enjoy anyway!
