Gnome Terminal Drag and Drop support

[Fernando Herrera <fherrera onirica com>]

	Hi!. I've just hacked a patch to add support for drag & drop uris
to gnome-terminal. 
	Various questions are opened:
		Just now, the code drop the protocol from the uris. Should we
do it only with local files?.
		We need to translate uri-format to something like bash-format,
for example: /mnt/media/My%20Pictures to /mnt/media/My\ Pictures
		is there a gnome funtion for this?

Salu2
