[PATCH] instaweb: support mod_cgid for apache2

[Mark Rada <marada@uwaterloo.ca>]

Some people have mod_cgid instead of mod_cgi, most likely as a result of
choosing a threaded MPM.

In cases where the user has both modules, mod_cgi will be preferred in
order to maintain a simpler setup.

This patch also causes instaweb to print a message and die in cases
where there is no module that instaweb knows how to handle.

	I thought I would squeeze this patch in while I was at it today.
