This shortens the name of the Package Loader in the desktop menu to "SqueakMap Catalog". It also adds "SqueakMap Categories" which is a slightly different UI to the same feature set.

Compatibility is also fixed with older Squeaks and older SqueakMap model code.
The re-open action is now also fixed to open a browser of the same class as before (possibly updated or replaced).
