Implemented script dependency handling
Added test-case of script dependency handling in ExampleModule
Cleanup of redundant getSceneCount calls
Properly get scene count in callGamemodeFunction
Remove unneeded TODO comment in shaders
Converted onMissionEnded gamemode func call to use callGameModeFunction function
Convert ExampleGameMode to be container-object based, and updated callGamemodeFunction to handle that
Correct import settings typoe so image suffixes are read correctly
Largely fixed companion image scanning when importing images and streamlined image-material interop during import preprocessing
Added handling for reading in PBR maps and creating a composite image + asset
Added WIP of Cubemap asset, and editing integration with a standalone cubemap editor
Added ability to create new Cubemap asset in Asset Browser
This makes some tweaks to the engine to support this, specifically, it tweaks the hardcoded shaderpaths to defer to a pref variable, so none of the shader paths are hardcoded.
Also tweaks how post effects read in texture files, removing a bizzare filepath interpretation choice, where if the file path didn't start with "/" it forcefully appended the script's file path. This made it impossible to have images not in the same dir as the script file defining the post effect.
This was changed and the existing template's post effects tweaked for now to just add "./" to those few paths impacted, as well as the perf vars to support the non-hardcoded shader paths in the engine.
