Message:: revamp fastcgi configuration: make it per-location this revamps the syntax in the configuration to better match httpd(8) (and in general be less weird) and to allow per-location fastcgi configurations. the bare `param' is now deprecated, but for compatibility it acts like `fastcgi param' would do now. Same story for `fastcgi <path�>'.
