inital ligttpd module for CPPSERV implemented

I finally got a semi-working ligttpd module. It took
a bit longer then I expected, but finally it does the basic work. I still need to add POST request handling, fix redirect support, and lots of other things, but at least there is something to look at.
Module is in master GIT tree in src/mod_cserv/lighttpd_cserv.c
