JSON structured menu for all facial expressions

The script has 19 facial expressions that can be chosen from a menu

The expressions can also be chosen by random and they can be played in a loop
The script can be used in a pose ball or in an attached (HUD)prim
When used for a pose ball the camera position is saved for next session

The script features a JSON structured dialog-menu

In this case the menu has one main page and three child pages
The power of JSON shows where the menu is decoded and in the navigation between menus. See the first lines in the listen event handler
