FileManager: Copy item(s) when dragging and dropping them :^)

Browse source 
This patch implements basic drag & drop file management in a narrow set
of cases. You can now drag & drop a file onto a folder in the same
directory, and the dropped file will be copied into the directory.

We'll need to support a lot more variations of this, but this is nice!
