Cool, but requires messing to much with every VC more or less. (And then 
I'd want to have Mercurial's numeric ids too, which aren't a 
short-version, but rather a repo-specific id that's sometimes useful.)

I'll make a filter for the revision id that shows a shortened version 
(12 chars) by default, but include the full rev in the HTML for future 
improvements. I suppose it could be improved to extract info from a 
SourceStamp instance, once it's there.

The plan is to write some javascript that shows the full revision on 
mouse-over. (This could allows to have a button somewhere on the page 
that swaps between short and long ids.)

For that, I'm planning to bring in jQuery, since writing plain 
javascript is a PITA.

Given that, I'll really have to look at getting cache control headers 
(expires, etc) in there. There was talk about a 'media' directory to go 
with the templates, and that is still a good idea. I just haven't 
figured out how to apply that best. In the meantime, setting an 
expire-time of 1 hour on everything served statically by BB is probably 
a good compromise.

Note that w/o javascript, thing will still work, you just have to click 
to the build to see the full rev-id. (or change the css..)
