Uninstalling adminpack

It's always fun installing new software. Sometimes though you need to
clean it out, for testing, because it's not needed etc.

Attached is a stab at making the adminpacks somewhat easier to uninstall.

The one question I had was on the LANGUAGE INTERNAL compatibility
functions, which I'm assuming earlier versions of pgadmin used?

Feedback welcome, testing probably neede.
