feat(auto_export): MORE experimenting, cleanup & analysis attempts

Browse Source 
* moved temp scene prefix to new 'constants' file, updated code accordingly
 * fixed, updated & refactored handling of auto export & gltf parameters
 * added additional tests to changed_parameters
 * added display of changes since last save in new side tab
 * more investigation & fix attempts for change detection...
 * various related tweaks & cleanups
