Added SIGTRAP signal handler to RailsFCGIHandler that'll force the process into a breakpoint after the next request. This breakpoint can then be caught with script/breakpointer and give you access to the Ruby image inside that process. Useful for debugging memory leaks among other things [DHH]

Useful for debugging memory leaks among other things [DHH] + * Update script.aculo.us to V1.5.2 [Thomas Fuchs] * Changed default lighttpd.conf to use CWD from lighttpd 1.4.10 that allows the same configuration to be used for both detach and not.
