Motivation for this change

This PR adds the top-level bluezFull package. This bluezFull package enables all the plugins provided by the bluez package.

It would be nice to have this bluezFull package for people that want to just get a bluez with all the bells and whistles instead of having to enable them one-by-one and compile bluez themselves.

I think this will mainly be used by people who want to use the Wiimote and Playstation 3/4 controllers over bluetooth without having to enable the individual options on bluez.

I called this package bluezFull after the gitFull package, but I am open to suggestions as to what it should be called. Another candidate might be bluezWithPlugins.
