Fixes the terrain asset creation, makes the loading logic go through the asset auto-import behavior when a filename or assetid is bound that is not found.
Corrects terrain material binding to properly save and load
Makes the terrain asset inspector fields work as expected.
Changed originalImportingAssets to originalImportingFiles in the AssetImporter for naming clarity
Made autoImportFile properly return the assetId that was made
Additional logging in the AssetImporter
Adjusted the asset registration logic to support reimports, which merely refreshes the assetID
Added logic to shape asset importing to be able to import in an existing companion constructor cs file
Tweaked the TSStatic setShapeName logic so it will properly set fields depending on if the assetID was correctly set, or if we have the noShape fallback in use
