Subject: C code for Chapayev's and Eino's request for a wall mounted "switch":
 if the player takes a swing at a solid grid (ctrl-direction at it), or it's
 hit by a solid-ish beam (normal thrown item, Magic Dart, etc), then a "wall
 hit" dungeon event will be issued for that square; a Lua marker can listen to
 that event to implement a switch/lever/button.

No Lua glue or Lua convenience classes yet.
