Added memory leak detection to "new" operator

Prevent merc in slot 0 from disappearing due to errant schedule.  Still need to find and fix schedule though
Prevent attempts to turn or climb roof when soldier collapsed
Fix problems when mortar or RPG randomly assigned to a soldier but cannot be added for whatever reason
Pathing favors beginning path on orthogonal and using as few turns as possible (mostly old behavior).
Prevent interruptions when soldier climbs up, which can cause fall into building just below the target roof position
Fix pauses due to soldiers hurt in previous turn
Fix soldier path not reaching destination when thrown by explosion damage or heavy gunfire
Restore pathing to cave and underground exits
Fix too many AI ending up on the roofs
