Subject: 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.
