Added Indoor Copper Refineries

Fixed Indoor Item Furnace: Is Interior Furniture set to True

Fixed issue with indoor well upgrades.

Split copper drills into their own building category to reduce inventory clutter.

Fixed an issue with certain researches (ex Iron Plates II) unlocking at the wrong level.

Added RTG
- Unlocked at tech level 5
- Produces a flat 30 power
- Insert power core into inventory

Added RTG II
- Unlocked at tech level 6
- Produces a flat 50 power
- Insert power core into inventory

These items are intentionally overpowered for three reasons;

-To facilitate base building in cities where the local power grid may leech power

-To give power generation options for planned features in tech level 7

-To provide players with a soft introduction to some of the new mechanics implemented in the mod.
