First draft of portals as a mod. Functional with defined Spawnables able to
spawn out of Spawners, that can set exactly which categories of stuff they
want to be able to spawn. Also did some cleanup and javadoc
Actually *activate* the new portals mod for being built
Quick bug fix for re-activated portals (currently don't know what to spawn, so they don't)
