fix(tools/gltf_auto_export): various fixes (#31)

Browse Source 
* fix exporter settings when changing blender project breaking the exporter
 * add auto creation of library folder if it does not exist (also any gltf export path where folders are missing)
 * main/level scene(s) now gets generated if there was no change, and they have never been generated before
