Dragging files into phpdesktop window

[GoogleCodeExporter]

How about adding support for dragging a file into phpdesktop window? There is 
the "external_drag" option on the ChromeSettings wiki page that disables 
dragging by default as it is not yet implemented.

See the "Dragging files into page" wiki page in node-webkit:
