Wild Horse Behavior

HotFix:

- You will no longer be able to lunge a horse that is being ridden by a player, and you will not be able to mount a horse that is being lunged, the mod will stop you. This will hopefully circumvent breaking the lead and horse requiring you to respawn it. 
- Foals can no longer try to nurse from stallions. 
- SWEM's eating goals now have much higher priority for horse goals. Horses should be able to eat, graze, and drink without being interrupted. 
- Pushing from other mobs/players should no longer interrupt eating/drinking. 
- Horses that are being crowded will now kick other horses away, which will prompt the ""corrected"" horse to briefly flee.
- Horses that take any sort of damage will stay away from the general zone it was kicked at for 3-5 minutes (prevents crowding)
- In a small enclosed space such as a stall, horses will no longer increase their gaits and will remain at a slow walk. 
- Horses in small enclosed spaces (nowhere with 8 clear blocks in any direction) may now lay down periodically. 
- Animation bugs that occur from laying down should be fixed, but if they still occur for you (likely due to differences in modpack), a laydown "lie_down" config is available to turn off the feature. Also inform me if it happens. 
- Horses now deal much less damage to each other outside of duels. This is to prevent personal space scuffles from getting horses constantly low on health. Horses are not able to kill other horses and they havent been able to; but before this hotfix they could get each other to 20% hp. Now the cap is 40% and damage dealt is much lower (from 8 to 0.8)
- Gestation now lasts 1 hour by default to match the 1 hour foal growth time.
- Colts and fillies who have just grown up have a 10 minute breeding cooldown.
- The natural_breeding config now functions as intended. If you make it false, horses should no longer naturally breed. 
- Foals can no longer be targetted by adult horse kicks. They didnt take any damage before but now the red flash/hurt sound/knockback won't occur either.
