Small bug-fixes

- If you happened to have multiple shop-keys or multiple legendhome-keys
  in your possession, only one of them would work - you'd have to drop the
  first, or put it in a sack, for the second to work. Now all of them should
  work properly.

- Failed bashes or kicks could be (ab)used as a substitute for "escape".
  Now, after a failed bash, you won't be made to sit, but you will experience
  a very short freeze.

- One bug that allowed equipment to be duplicated during a crash was fixed.
