Earth Additions

Added Several new mods to enjoy, mainly focusing on two things:

1. Fixing spawn rates with custom mobs
2. Adding new tech tree (Electrodynamics) with advanced explosives and cross compatability with Mekanism (energy sources and such are now convertible)

Mod count now up to 69. If you have any suggestions for further updates and developments / bug fixes, then please, make a comment or dm me. Thanks!
