Crash when checking a tile for explosion effects
Merge branch 'v0.5.0' of github.com:DanaL/crashRun into v0.5.0
Added a debug command to let me activate inactive lifts
Replaced leftover call to old __split_message() function
Cleaned up the code for message when monster is killed.
A few tweaks to battery stuff:
	- items can have batteries changed while equipped. No idea
	  why I decided to disallow this at first, but it's really
	  annoying in game.
	- different targeting wizard message if you equip it while its batteries are dead.
	- moved code for handling the battery change from the DungeonMaster class to the
	  BatteryPowered class itself.
Added a message to indicate success or failure of mathematical attack; made them slightly more effective.
