ChangeLog: 

Add support in Pidgin for playing back audio:// links. Also include a "Save
File" menu item to save a permanent copy.

Playback uses purple_sound_play_file, which uses a playbin. This will not
correctly play back the Siren codec until Bug 588218 is fixed, but that
looks like it will be soon.

Also, if anyone has a better idea for GtkIMHtml->PidginConversation than
g_object_[gs]_data, feel free to fix it.

References #393.
