Initial Makefile

OK, so this is the Makefile for the pbxopkg package.

@MaStr should I leave you as maintainer?

How should the **TITLE** be for menuconfig? I called it *PirateBox-pbxopkg* for now. I am also not really sure about category, I just put it where the other piratebox related settings are.

Interesting side note: The *Package/pbxopkg/install* method is not allowed to be empty, if it is empty no ipk is generated, I just inserted a comment and the ipk built without problems.

No need to merge it right now, just wanted to ask those questions ;-)

I think the latest version is 0.0.6 

This is a package change, so we should change the version numbering to something different.

I suggest 0.1.0
