Actor Based Action Icons for YEA FTB
Made by: Sixth
Requires: Yanfly's Free Turn Battle script

This little snippet will let you change the action amount display in Yanfly's
Free Turn Battle script.
By default, all of the actions use the same icon, but with this script, the
action icons can indicate which actors have some actions left and which of them
used up their action points already.

You can setup a custom action icon set for your actors by using this note-tag
on them:

  <ftb icon: normal_icon, used_icon>

Replace the normal_icon part with the index of the icon for unused action
points.
Replace the used_icon part with the index of the icon for used action points.

If an actor got no such note-tag, it will use the default icons setup in
Yanfly's FTB script.

Place this script below Yanfly's Free Turn Battle script!
