Removed the old SHAPE_ASSET macros
Implements AssetRef struct that acts as a universal wrapper for an templated AssetPtr and AssetId pair
Adds Type handling for AssetRef for ShapeAsset to unify handling in classes that utilize a shapeAsset, so assigning an assetPtr or an assetId will keep a record of the assignment in the event the assetPtr is invalid.
Update all classes that utilized the old SHAPE_ASSET macros to utilize the AssetRef struct and updated the class code to utilize it to provide much more clean and concise code that isn't blocked behind macro definitions
Added a new example class: shapeDatablockExample which allows render of a simple shape object utilizing a simple example datablock.
note this *does* require a baked skylight in the main scene
todo: track down why a similar protocol does not operate for guimaterialpreview and guiobjectview
Processed core, tools and default modules to utilize assets
Converted all console types that were string based, such as TypeImageFilename to utilize const char*/the string table, which avoids a lot of type swapping shenanigans and avoids string corruption
Removed unneeded MainEditor mockup module
Removed some unused/duplicate image assets from the tools
while not a major issue per-se, the sheer number of times the engine has to jump back in memory and backfill data in a given class can add up. First run of... many.,
