Got FollowPath2 to a working state.  Still needs to detect when it's off the path and recalculate, though.
Added resetOnStatus decorator
Now, when set(t: T) is called on IntInput and Vec3Input, they change their text fields to display the new value.  All inputs should probably do this, but I only use set() on Int and Vec3 Inputs right now
Changed Playback node's constructor to call-by-name, so when the node gets reset, it can get a new sequence of inputs to run.
BTBotExperiments: Improved description at the top of the file.  Deleted the stuff that got turned into HuntCreatures.
new behavior: randomlyWiggle.  Also, improved pathfind test.
