rathena/src/map/path.h
ultramage 49f1f4434d * Reorganized the contents of the mapserver's header files.
- map.h is no longer a generic dumping spot of all the shared structs, and instead, each such structure now resides in its logical component
- map.h now only holds mostly map-related things (needs more cleaning)
- there's still a lot of room for improvement (reorganization within individual header files, etc...)
