Subject: 23.1.90; Patch for OS X drag-and-drop

Hi,

I made a patch on the latest emacs git repository, I guess this is 
mirrored regularly from the canonical repository?

The patch modifies emacs to accept all dropped urls, not just 
files. The file-url behaviour should be unchanged, but when a 
non-file url is dropped it sends a new event with the text of the 
url, which by default inserts the text. Maybe a new event isn't 
necessary, and it could be treated as dropping text?

The patch is included below, and is also available at 
http://gist.github.com/260042

Thanks,
Bodhi
