Not looking forwards to porting this - it may take a while.
Need to add the keystone and portal activator item back.
Need to add the offering altar back for the gem.
The teleporter code will have to be changed as it is a port from before @purpleposeidon 's portal was implemented - but it should be easy enough to 'fix'.

added the one @purpleposeidon made when I released :)

added old one back -it works.

@purpleposeidon - don't worry, your beautiful work will be added back once I figure out other things.
It's been a long time in the works and there is much more to go :P
