Mod «Biotech Mech Stuff Elongated - Mechanoid Upgrades» for Rimworld (v1.4)

This mod adds a few buildings that apply permanent [well...until they die that is] upgrades to nearby mechanoids.
Currently available upgrades:

• Armor
• Movement speed
• Combat
• Energy efficiency [consume less power and generate less waste]
• Processing power [consciousness]

The upgrade gets applied once a mechanoid spends enough time within the building’s range [can take a bit, it should still take less than an in-game hour, done to prevent just that little bit of lag].
Each upgrade consumes a bit of the building’s “fuel”, the amount depends on the upgrade’s level and the mechanoid’s weight class.
The fuel can be replenished using mechanoid upgrade cells [craftable at the fabrication bench, can also be salvaged at the smelter].
The building allows the player to choose which mechanoids are to be affected.
Currently available settings:

• Allow light class mechs
• Allow medium class mechs
• Allow heavy class mechs
• Allow ultra-heavy class mechs
• Allow combat mechs
• Allow worker mechs
• Set upgrade level [1-3]

The building starts with only one available upgrade level, additional [2] levels get unlocked with further mechtech research.

The current cost of an upgrade cell is:

• 14 steel
• 6 Plasteel
• 4 Gold
• 8 Uranium

The cost gets multiplied by the upgrade’s level:

• 1x for level 1
• 2x for level 2
• 3x for level 3

And the mechanoid’s weight class:

• x1 for light
• x2 for medium
• x5 for heavy
• x8 for ultra-heavy

The upgrades do disappear on death sadly. I could make them stay, but reviving a mech removes all health conditions from it anyway.
The actual stats of the upgrades might still require some work, I’m still not 100% sure whether an x160% boost [on level 3] to armor is overpowered or underpowered considering the cost.
I’m open to feedback on this one.

• The DLC is the only requirement
• It should work with all vanilla and modded mechanoids [unless they add their own weight classes or somehow
  count as neither a combat or a worker mech]

Requires: DLC Biotech
