[crossfire] Rods bug

[David McIlwraith]

Hi guys,

The bug that was fixed in relation to rods (the rod power being capped
to the "use magic items" skill level) is now broken again, which is
readily evident on Metalforge using the current 1.x SVN. Obviously,
this is prone to extreme abuse, allowing low-level players to very
rapidly gain experience with, for example, a level 110 rod of
banishment. Can someone please fix this ASAP?

Thanks.
