XLining.TEMPERATURE_REGULATOR needs lang keys

[KameiB]

Hi!
I'm translating RLCraft (Minecraft 1.12.2), which includes armorunder-mc1.12.2-1.0.0 and realized that in the file:
LinedArmorTooltip.class
Line 30: String what = defn.value == 0 ? "MILD" : (defn.value < 0 ? "COOL" : "WARM");
those texts are hardcoded.
If you have the chance, could you please add lang keys for those?

Thanks in advance and great mod!
