Advanced prone locomotion layer(3.0)

A 3.0 locomotion layer that lets you switch between different laying animations.
[credit to Manish for sitting animation]

To use, simply attach the "tranquilbase" controller to the avatar's base locomotion layer, the tranquilparams to the parameters and Locomotion to the menu(or make it a submenu of a larger one if necessary)

--note: in order to use this with avatars that have existing menus, you need to do as follows:

1. In the avatar's expressions parameters, add a "supine" int value
2. In the avatar's menu, make sure that somewhere you have toggles that change the value to:
   -0 for default
   -1 for laying back
   -2 for sitting
   -3 for laying on side(right)
   -4 for laying on side(left)
