Negative revisions for changeset

We use a continuous integration server that tags successful builds, so the last revision against trunk is generally useless for seeing what actually changed. A tiny change, and we can now view revisions using a negative counter, e.g., http://ourserver.com/trac/Project/changeset/-1 now brings up r1393 if r1394 was current.

Eventually. In the same vein, as we're already supporting head, there are also the git-like shortcuts: head^, head^^, head~3.
