WelcomeInfo mod for Minetest, code should have been condensed at the time.

welcomeinfo.lua

--------------------------------------------
--WelcomeInfo mod by CraigyDavi and crazyR--
--------------------------------------------
--TO DO
--Condense code and make it easier to edit the text using variables.
--Release as a mod.
--Revoke interact when frozen and grant when unfrozen.
--Anything else?

--Please note that at the moment this will not work using a mobile client! *I think*--
