New PHPerl - the only way to run Perl CGIs

CGI.pm changes its behavior when executing under mod_perl, and also sometimes saves its own copy of the query state and resumes that state on re-entry. Previous alphas of PHPerl only partially accounted for this special behavior.

Note that PHP's ``virtual'' function has the same problems with CGI.pm. PHPerl.pm now provides the only correct interface to execute Perl CGIs from within PHP.
