Arcane Synthesia

Sorry for the quick uploads! I found a fix for one of the bugs, even though it's really a fix per se. It is a mod that converts energies.
Also a fix for the Biomes O' Plenty for the server side, go into the server cfg file and change the world gen to "BIOMESOP" and it will generate the new biomes.

Added Mekanism as well.

I disabled Advanced Generators because of client side issues, but it is probably enabled by default in your modpacks, you will probably need to disable it to get it to work on a server. I'll upload a server download in the next big update.
