Feature Request: Drag and drop folders

[mfbulut]

Currently, dragging and dropping a folder results in an error like "Couldn't load file 'C:/Projects'."
Instead, dropping a folder should open it in the File Navigator (Ctrl+O Menu)

It would be useful for navigation through deep directories.

It's a good idea, but some people would expect the folder to be added to the current workspace when dropped. We should probably have a dialog or a switch in the config for that.
