ToME: the Tales of Maj'Eyal

If my annihilator's mecharachnid equips some armour (heavy, massive, etc.) then takes it off, it retains its Dex requirement to wear rather than reverting back to Strength. (So in essence my annihilator can also equip armour based on dex rather than str.)

Steps to reproduce:

1. I find some massive armour that I'm unable to wear because of Str requirement [I'm a really clever orc, but not particularly strong]
2. I give the armour to my mecharachnid and switch to take control of my mecharachnid (via the standard party UI, not the talent)
   2a. In my mecharachnid's inventory, the armour now has a Dex requirement to wear, rather than Str
   2b. If my mecharachnid gives the armour back to my annihilator at this point, the armour reverts back to a Str requirement, as expected
3. I have my mecharachnid equip the armour. [At this point the armour's Dex requirement has become permanent]
4. Give the armour back to my annihilator. [Now my orc can wear it because the req remains Dex]

Thanks. I've got an open merge request for other EoR fixes so will investigate and resolve this.
