Archery woes (review?)

Since Shoot talent does not account for the run-out ammo in its pre_usee and just returns nil from action in that case (I believe that is intended for either player misuse or difficult scenarios), and as error message of not having one of two things equipped in exactly the right fashion have always been the same confusiong snippet through all archery talents, I've decided to unify the pre use check for all archery. It comes in two fashions, counting wardens in and not counting wardens in; if desirable, those could be joined for added adventurer benefit, but I just left things as they are. Playtesting suggests it indeed is working as intended now. If there's anything to add to the picture while I'm at it, or if there are any problems, please comment.
