WINTERMUTE: Add FoxTail actor walking methods

There are two new methods: immidiate stop and changing walking speed
For stopping, I'm reusing turnTo() code to finalize moving.
I talked to FoxTail devs about what SetSpeedWalkAnim actually does and answer was to set animation delays with given number of milliseconds.
