There are some base libraries that should be used in common.  Notable
the Enlightenment Foundation Libraries (EFL), LuaJIT, luaproc, and
lemon.  Other external open source projects that we just use directly
should go here to.  Makes it easy to compile it all.

Note that in some cases, there might be changes.  Such changes should be
documented.

luaproc has been hacked up a bit, and will continue to be hacked up. 
Merging it into LuaSL, and converting it to EFL.
