* The Race Against FF upload.  Merge from unreleased Debian git.
  Remaining Ubuntu changes:
  + debian/patches/05_disable_resize_grips.patch.diff:
    Disable resize handles for the Do windows.
  + debian/control:
    Bump gtk# build dep for HasResizeGrip API.
* New Debian changes:
* The long fortold release
  + Fixes a threadsafety issue resulting in 100% CPU usage (Closes: 565591,
    LP: #450852).
  + Proxies all keyring calls to the GTK main thread, as required by the new
    gnome-keyring (Closes: 603876, LP: #553643)
* debian/patches/00_bundledlibs.dpatch:
* debian/rules:
  + Upstream has dropped bundled gmcs binary; now 100% DFSG-free, so we don't
    have to repack the tarball or patch the buildsystem.
* debian/patches/03_disable_docky.dpatch:
  + Drop.  Docky is now gone in the upstream tarball.
* debian/rules:
* debian/control:
* debian/patches/*:
  + Switch to quilt to harmonise with other pkg-cli-* packages.
* debian/control:
  + Drop recommends on gnome-do-docklets.  Docky is now a separate package,
    so the docklets are useless for Do.
  + Bump Breaks on gnome-do-plugins to 0.8.3.  Do no longer provides the Wink
    library, which has been imported into the 0.8.3 do-plugins sources.
  + Bump standards-version; no changes needed.
  + Migrate to git and update VCS fields appropriately
