Actions fixes

[NQNStudios]

• "Finish what you're doing first" comes up a lot in the text buffer. I wanted to add such a message to a new case but couldn't remember how to match the ones that are already in there. Solution: Make it a constant. Also, standardize existing messages so they all prefix with the attempted action.
• The menubar "Do Alchemy" button passing an 'A' key could have unexpected behavior, i.e. in talk mode, clicking "Ask About". Fixed this
• Don't know if the menubar "Wait" button could cause a bug by passing 'w', but fixed the kludge regardless. Also, some code paths of "Wait" would no-op silently. Fixed that.
