New feature request: Water mobs fix

Hey there, the plugin is really good, totally awesome on land, but could you add some features for aquatic pets? currently they act just like a horse. -They are mountable on land -Sometimes you are kicked off the mount -They wont't go underwater -They are a lot slower than on land (For testing i used the last version of simplemobs and API from jenkins and 1.13.2 spigot.)

I'd like to be able to go underwater & not be able to mount them while not inside water. The speed thing isnt a problem because you could just put a really high speed on the config file, if you couldnt ride it on land.

Best wishes and good luck! :)
