LazyCat Z-Level Solution

This is what was written but I'm not familiar with the trap coding so this may have been short hand and LazyCat wanted it as:

keys.clear();
id++;
keys.push_back("null");    
traps.push_back(TRAP("airhole",    		'.',	c_ltcyan, 0, 99, 99,
	&trapfunc::airhole,	&trapfuncm::airhole,
	itm_null, NULL));

Not sure...
