v18.6.0

• Enemy and friendly NPC mounts that have their rider thrown off will no longer become wild animals, but instead they will keep fighting until one of the following happens:
  --> Their rider remounts the animal (riders will now attempt to remount their animal whenever possible).
  --> The rider owning the animal is killed or downed. In this case the animal will flee in panic and leave the map, as there's no longer a master around to control it.
  Note: When facing a dangerous mount, it's now more important than ever to kill its rider, so that it starts fleeing.
• If an enemy mount is downed, it is now turned into a wild animal so you can still tame or hunt it.
• A lot of code has been refactored and moved from/to the other mods in the series to prepare for the next mod release.
• Updated spanish translations.
