Katze quest: use bitmasking to be able to remove the variable LastHiss.

Nibble 0: Progress of quest
Nibble 1: what was saved previously in LastHiss
Add LastHiss to clear_vars

Since the value in LastHiss is only needed to get some hint from Alice,
taking over the value from LastHiss to Nibble 1 of Katze isn't needed.
