* Extensions are now scanned and loaded on demand. * Extensions found are cached into a file that is used to load them (which is also exported). * Editor will ask to restart when an extension requires core functionality. * Editor will attempt to load extensions always before importing or loading scenes. This ensures extensions can register the relevant types.
