New sharing UI update

Even though the current status is best gathered from bugzilla, I'll post a few teaser screenshots to whet your appetite.

Sending to Twitter/Twitpic

Sending to Flickr

The interface will see a "folks" based sending item called "Contacts" at the top of the sidebar, and we should see some more services and devices appear as well, as libsocialweb gains support for them, and old nautilus-sendto plugins are ported.

More when those pesky upstream bugs are fixed.

nautilus-sendto plugin API

As promised in the nautilus-sendto module proposal, I fixed up the plugin API, wrote API docs, and exported the plugin functionality.

I've already patched Empathy to carry its own nautilus-sendto plugin, and will be moving the Pidgin and Bluetooth plugins in the near future.
