[1.6.4] Mental stimulator overrides bonuses in item names

[Velorien]

I had an iron helm of strength (+3). I put it on with a mental stimulator, giving it +4 CUN/+3 STR. When I took it off again, it now read +0 CUN/+3 STR (which is a long-standing bug in itself), and the item name was iron helm of strength (0).

Probably related to the bug that sticks whatever number comes "first" (in the code) into the item name, even if it's not related to the words next to the parentheses.

Examples of that would be items like a Verdant Robe of Fire (+8%) which gives +20% / +10% fire boosts, but +8% vs. blight or nature.
