The touch event is used only for the sleeping engine (it will be used for dimming later) and it was transferring all the json info with page name, component, entity, etc.
This was replaced by a simple random integer with no meaning other than "the screen was touched, reset the timer".
- Removed a bunch of unused pics
- Changed page indicator to new format (which will allow future development to hide unused pages)
- Standardized close button in most pages
