Instance Dungeons Update

As requested by the community in http://hercules.ws/board/topic/1702-implement-rathena-npc/ we're merging in the latest of rAthena's dungeons, this includes the rewriting of all instance dungeons and the addition of 4 dungeons that were not present previously (BakonawaLake, BangungotHospital, BuwayaCave and OldGlastHeim).
Update also includes the ability for instances to reset (or be destroyed if instance files were disabled/removed) upon @reloadscript, instance scripts are able to control to what stage the instances are to be reset via the instance_set_respawn (reload spawn) script command, OnInstanceInit labels are now triggered when the instance starts via instance_init (and upon reload), they may be used alongside instance variables (which are persistent to @reloadscript) to save players' progress.
