Equipment statuses interfere/cancel regular statuses

[kiedtl]

(This is a bug that I noticed a while back and recorded, where "a while back" is 1-2 years ago. I don't know if it still exists or not, though it likely does.)

Basically: if the player has a Tmp status, and then equips/dequips something that grants the Equ version of that status, the Tmp status is also canceled because the Equ status overwrites the Tmp status.

Two ways to fix it:

• Painful refactoring, store statuses in a vector instead of an enum array
• Ignore it and ensure it never happens in practice. I.e. don't add pieces of equipment that have statuses that could be inflicted by other means in a temporary way.
