Title: Fix for cases where a module may be installed that doesn't have a config.xml

I think I hit this once when there was a module
that was installed in app/etc/modules but didn't have any actual module
directory or config.xml.

Then again, perhaps it's best to simply disable any module that doesn't have a config.xml b/c it should be impossible that they'd be doing anything at all.
