[PATCHES] improve extensions support

[HacKan]

Well, you can't override more than once because you can't have 2 files
with the same name. This allows users more freedom, they can choose to
use internal commands or extensions. The pass core isn't touched.

Current extensions are not affected at all. Also, users wanting to use
an extension that normally overrides an internal command without doing
that can simply rename the extension file.

I believe it provides more usability and alternatives without changing
the pass core. Those who want to use pass w/o extensions can do it;
those who want extensions can have them; those who want extensions that
override internal commands can have them too. What's wrong with giving
the community that?

Cheers!
