- Added state.running to unit_data to make it easier to check for running characters (saves having to get the sc data and check for the corresponding timer all the time)

- removed pc_run, pc_walktodir, replaced with unit_run. 
- moved the code that makes you walk that extra cell to unit_stop_walking, which is now invoked before resetting the walk-target.
- Flag &2 in unit_stop_walking is now to make the character force-move that extra tile if the walkpath pos is 0 at hit time.
- Added variable walk_count to unit_data to be use as a counter for cells walked for walk-triggered skills (walk path_pos is not good enough since it keeps resetting each time the walk path is updated)
- Increased WALK_SKILL_INTERVAL to 5 (it is the closest value that makes the average mob trigger a chase skill every second)

 IF YOU HAVE A WORKING AND TESTED BUGFIX PUT IT INTO STABLE AS WELL AS TRUNK.
 
 2006/04/17
+	* Some cleanup in the TK_RUN related code. [Skotlex]
+	* Added variable walk_count to unit_data to be use as a counter for cells
+	  walked for walk-triggered skills, on-chase skill triggers are now done
+	  every 5 cells (it is the closest value that makes the average mob trigger a
+	  chase skill every second). [Skotlex]
+	* mob_skill_db needs updating since it's current use rates for chase-skills
+	  assume the trigger is every 100ms rather than every second.
 	* Fixed TK_RUN having a cast-bar when attempting to stop-running and
 	  generating timer_delete errors when halting as well. [Skotlex]
 	* Clearing the dummy npc after fooling the client. [Lance]
