* Enable import J3O model feature, assets with absolute paths are copied as-is, whereas the model and relative assets are copied to the user selected folder

 * Add dummy ProjectAssetManager feature to support ignoring absolute paths when loading from disk (necessary for the above)
 * When gathering the asset list for a model, support ignoring absolute paths
 * Added destination folder letter case fix needed for Windows when importing absolute path assets, it will use heuristic to match some asset against the import path and if so, change the letter case to match that of the asset.
