* Sync with Debian. Remaining changes: 
* debian/control.in:
  - Drop build-depends on libepc-ui-dev and libgrilo-0.2-dev (in universe)
  - Drop libxtst-dev build-depends so that the (redundant) fake key presses
    for inhibiting the screensaver are disabled (LP: #1007438)
  - Build-depend on libzeitgeist-dev
  - Suggest rather than recommend gstreamer components in universe
  - Add totem-plugins-extra
  - Add XB-Npp-Description and XB-Npp-Filename header to the 
    totem-mozilla package to improve ubufox/ubuntu plugin db integration 
  - Refer to Firefox in totem-mozilla description instead of Iceweasel
  - Don't have totem-mozilla recommend any particular browser
  - Drop obsolete python library dependencies since iplayer is no longer
    included
* debian/totem-common.install, debian/source_totem.py:
  - Install Ubuntu apport debugging hook
* debian/totem-plugins-extra.install:
  - Universe plugins split out of totem-plugins (currently only gromit)
* debian/totem-plugins.install:    
  - Skip the plugins split to -extra and add the zeitgeist plugin
* debian/rules:
  - Build with --fail-missing, to ensure we install everything. 
    + Ignore libtotem.{,l}a since we delibrately don't install these.
  - Re-enable hardening, make sure both PIE and BINDNOW are used
    by setting hardening=+all. (LP: #1039604)
* debian/patches/91_quicklist_entries.patch:
  - Add static quicklist
* debian/patches/92_gst-plugins-good.patch:
  - Build without unnecessary gstreamer1.0-bad dependency
* debian/patches/93_grilo_optional.patch:
  - Allow building without grilo while grilo MIR is still pending
* debian/patches/correct_desktop_mimetypes.patch:
  - Don't list the mimetypes after the unity lists
* debian/patches/revert_shell_menu.patch: 
  - revert the use of a shell menu until indicator-appmenu can handle
    the mixed shell/traditional menus itself
