Fixed Configs + Dinos in Dimension

Changed IDs of blocks and items to allow for config - need to reload
config files and might need reload of worlds; should be last ID change

Made the Fossil reappear in the creative tab

You can now allow dinos to spawn in the PaleoPlains biome (in the
Paleoplains dimension) by editing config
Before update to 1.5.1 - Bugged!

Some dinos fall through ground. Gonna test when have a spare moment.
Rest should be good and dimension unloaded along with items and blocks
