Added patches and other changes from version 12.10.0.1-0ubuntu3

Fixes https://github.com/linuxmint/indicator-sound-gtk2/issues/1.

Clem, I haven't added debian/changelog since it would overwrite your own message in it, but just in case, here's the portion of it that's relevant:
```
indicator-sound-gtk2 (12.10.0.1-0ubuntu3) trusty; urgency=low

  * Make this actually work. (LP: #1208204)
    - Make the Gtk2 indicator use a different DBus name, so that the
      indicator-sound-service from this package is loaded instead of
      the Gtk3 one which is incompatible.
