Derpy's Kat Pack

- Removed Spartan Weaponry (for real this time). Lack of Tetra compatibility killed it.

- Removed Mekanism and the generators addon. It just felt so... Disconnected, especially when you also have Create to work through.

- Removed Mystical Agriculture. I had never played the mod before and had no idea it was so absurdly grindy (and with so much overhead!).

- Added Ice and Fire for some roaming boss encounters with good loot (and bonus Tetra compatibility!).

- Added Blazt's simple generators as the anti-strip-mining holdover until I find something better. Its' self-proclaimed overpowered so it probably won't stay forever.

- Added Farmer's Delight for more farming options.

- Added Flat Bedrock because flat bedrock is infinitely better than not flat bedrock.

- Added Unified Resources because at this point we somehow have three different versions of copper floating around.

- Reverted back to Beta versions (just a title) because I realized I'm not quite ready to proclaim this as 1.0 yet.
