Title: Package Handle Added Twice

getAttributeTypeURL does not returning the current URL for packages.
This is because $dirp adds the package handle but then file_exists
checks $dirp . '/' $pkgHandle
Which ends up with the package handle added twice and always fails

Therefore all packages that have custom attribute types(like core_commerce) appear to be failing at loading things like type_form.js and type_form.css and similar type issues.
