 ProjectLibrary
  - Save/Load - saves/loads the hierarchy of ResourceEntries
  - import(filePath)
    - Check if we have an importer that supports the resource with the specified extension
	- If we are okay then import the resource, otherwise do nothing and return false
	  - Check if importer failed and report error if it did, also return false
  - move(oldLocation, newLocation)
    - Moves the resource from one location to another, first performs the move on the disk, then updates the hierarchy
	 - Potentially suspends file monitoring since we don't need to detect these changes?
  - remove(location, subfolders)
    - Removes the resource from the file-system, and the rest is handled by the auto-update system
  - monitoring
    - Sets up a FileMonitor at the Resources folder, and calls add/move/remove/import whenever changes are reported

ResourceManifest contains absolute file locations. What happens when the project moves?
 - When saving ResourceManifest make sure to process all paths and make them relative.
 - Then reverse that process on load

What happens when importer fails importing a file?
 - This can be one of the lasts steps, but I will likely need to go through all importers manually and set them up so they return proper error codes
    and clean up properly on error.
	- In fact they should use exceptions but those should be translated to error codes when returned to Importer
	  - OR just write directly to debug log?
	   - Probably log and error code, since I will need to inform the outside world that import failed somehow

--------------------

IMPLEMENTATION: First ensure scan and import works. Then work out how to deal with FileMonitor. And finally how to add/remove/move resources from outside.

Don't forget meta files and a way to store import options.

I'll likely need to update ResourceEntry in ProjectLibrary
 - Replace UUID field with ResourceMeta class
    - Contains UUID and ImportOptions
	- Created whenever resource is imported
	- Deleted when resource is deleted

Make ProjectLibrary also check for .meta files that have no corresponding file and delete them (With a warning logged)
