(5.1.1) Tropicraft v5.1.1!

Hey everybody!

Here are some bug fixes for the latest release:

– Fixed bug where nothing generated in the overworld because I messed up a boolean (if you have this bug, simply upgrade to the newest Tropicraft and delete your old Tropicraft config!)
– Fixed coremod rendering (thanks cpw and zeldo :D)
– Added warning in portal that lets you know if you need to drink a pina colada in order to teleport
– Fixed encyclopedia gui bug
– Added biome ids to config file
