Jimmy can be hammered

@lakhnish Seems to be intentional, can't see how the devs would "accidentally" put references to the workable component everywhere in Jimmy's code .

The idea behind being able to hammer him is like Walter's tent, or Warly's portable crockpot. Only those characters can dismantle those structures, but if need be incase they leave the server, other characters can hammer them.

Makes sense!

A problem I experienced was that hammering is the default action when holding the hammer, so when you try to learn the new recipe and click on Jimmy, you will hammer him (if you press the space bar you won't hammer him).

Also, when you hammer Jimmy he will forget the research he's done and will turn as if the item was dropped on the ground. 

Changed Status to Fixed

Although the hammering was intentional, I decided to change the design around it so that the hammering is no longer necessary, due to the action priority issue mentioned above.
