Plugins Eye Saccades

I was made aware that some people prefer to set the default eye offset lower than 0. Therefore I've slightly expanded the up/down range selection to allow this.

I managed to convert this from a plugin preset to an actual plugin (After a lot of trial and error ?).

Now you can just load it onto any person atom and it'll automatically start working. I've also simplified the UI and set some boundaries to avoid anything too crazy.

Should be a lot easier to use than the plugin preset.
