allow subscript loader to work on unpacked extension

[tumpio]

Sub script loading did not work on unpacked extension.

Why will you unpack it? This extension is supposed to work as packed extension only.

I unpacked it so that I could modify it and test it at the same time while it is installed.

How are you doing it?

Nevertheless, that patch makes sense. You shouldn't have to fiddle with directories and and URIs (especially involving jar files.)

You shouldn't use .jar files anymore anyway, as the extra layer of compression actually reduces performance.

Thank you @wagnerand ! 👍

Well I leave it open then, @scrapmac can decide if you want it.
