[Catalyst] Lighttpd fixes

[Andy Grundman]

I've checked in several lighttpd things tonight.  Thanks to a post from 
Mark Blythe a few months ago [1] we've got a fix for the weird PATH_INFO 
vs. SCRIPT_NAME issue when running under lighttpd.

I've checked in 2 test scripts for testing the full Cat test suite 
against lighttpd in both root mode and non-root mode.  According to 
these, all tests pass in both modes now.

If anyone uses lighttpd and was having problems, I would appreciate it 
if you could try the latest trunk (r5192) and see if it solves your 
problems.

Thanks,
-Andy
