Gitweb is active

I finally got around to setting up gitweb for Math-GSL, it was simply a matter of reading the source of gitweb.cgi to understand what it was doing and figuring out that "git" was not in the $PATH of my webserver.

Make sure to check out the "bleed" branch for the latest development. I am gearing up to put our first release on CPAN to see how the CPANTesters put it through the gauntlet. It will be interesting to see how many of them meet the build requirements of SWIG+GSL.
