Fix for bug 97721: Bugzilla now requires Perl 5.005 (previous requirement was Perl 5.004).  This is due to the use of Template Toolkit for templatizing the pages for easier local customization.  The new attachment tracker that was checked in earlier tonight uses the templates.  Also included on this patch is a check for AppConfig, which is a prerequisite for Template Toolkit, because the Makefile.PL for Template Toolkit won't run without it, and it doesn't tell CPAN that it has prereqs, which causes confusion if you're installing from CPAN.
