WIP: characters walking & climbing (Patreon)

Quick look at the work in progress follow system in Alive v73. I added floor detection to the characters feet to detect surfaces with collision. This way, characters can climb on things, even stairs, on any of the existing vam maps out there.

There's also dynamic speed. Characters will move faster when far away from the player. To enable or disable characters following you around, there's a new button in the UI next to the Automatic Behavior toggle, as can be seen in the video above. This functionality works with 2 characters as well: it's possible to have two models following you around at the same time, an earlier work in progress video with that can be seen here: https://www.youtube.com/watch?v=CSJsXUxt1vE
