- Monsters will now properly run away when using NPC_RUN (fixes#7941)
- Introduced a new function unit_get_walkpath_time that returns the time the unit needs to walk its current walkpath
* This is now used for NPC_RUN and random walking
- Fixed an issue with mismatching timer warnings when a monster casts NPC_RUN multiple times in row
- Monsters will now always attempt to use non-berserk-state skills once per second (fixes#1700)
* This completely replaces the "ugly" solution to use a walk_count for idle, walk and chase skills
* This interval is now a lot more accurate and no longer influenced by external factors such as canact delay
* This interval is now also used for lazy monsters rather than MIN_MOBTHINKTIME*10 so that MIN_MOBTHINKTIME can be reduced without having to worry about skills being cast more often
* Angry skills no longer replace the normal attack and now follow the once per second rule; they will always first be attempted at the end of the walk delay after a normal attack
- The special follow-up attack skill monsters use when you move out of their attack range, now is only used when they are in Angry state
* Also fixed a bug that this was checked every 100ms until the monster used a skill, instead of just once per second
- Monsters now can use chase skills even before they start moving (assuming one second has already passed since last skill check)
- Removed "hack" to make monsters cast chase skills when trapped in icewall
* This was solved by implementing checking for chase skills before starting to move
- Monsters will now receive an aMotion walk delay after having used a skill
- A monster that could not walk randomly because of walk delay will now walk immediately once the walk delay expires
- Using angry or berserk skills will now set a monster's attack delay
