Add compatibility for running ./console with php-cgi by setting SERVER args from GET parameters.

As title. Tested `php-cgi ./console list`, `php-cgi ./console help tests:run`, `php-cgi ./console test:run Core_OptionsTest` and `php-cgi ./console core:archive --url=localhost`. No output received on last one, but logs show archiving succeeded.

What do you think @tsteur?
