[PATCH] Exporter for code_swarm

This simple Perl script echoes the entire project history into a format
suitable for consumption from the organic project development visualizer
code_swarm http://vis.cs.ucdavis.edu/~ogawa/codeswarm/ and any other
software that expects a file event XML file in the same format.

I had actually considered writing a patch to add the format as a predefined
format for git log, but on second thoughts I decided it was not really worth
the effort. This script, although it's just a quick hack, serves the purpose
just as well, although it's obviously not suited for anything more than
contrib/, if for anything at all.

Enjoy.
