[patch] Fix FastCGI documentation in the shared-hosting case

[James Crasta <jcrasta@…>]

When I wrote the fastcgi documentation, I mistakenly put in leading slashes on the RewriteRule, which will not work when using mod_rewrite in .htaccess; This patch fixes that documentation.

Also, I made a small one-line change to core/servers/fastcgi.py to allow it to take keyword-args, updated the documentation to reflect.

FastCGI documentation fix

[Adrian Holovaty]

(In [3759]) Fixed #2732 -- Fixed error in FastCGI docs and added keyword-arg support in a FastCGI function. Thanks for the patch, James Crasta

Minor fix to allow the first argument to runfastcgi to be optional, thus making calling it with kwargs useful

[James Crasta <jcrasta@…>]

I realized that adding the cleaner kwargs syntax wouldn't be all that useful if the first argument to runfastcgi was still required... you'd need to pass an empty list then. I added a one-line patch to fix that.

I figured since this is related to the same addition, I'd just reopen the ticket rather than creating another
