Install in /usr/lib/firefox-3.0 instead of $pkgver (FS#11769)

    Add mime-types and shared-mime-info dependency (FS#10419), add patch to fix GNOME background color parsing (FS#10836)

Remove firefox.sh, the xulrunner stub is fixed for FS#10737 now. Build firefox without fakeroot so X doesn't need to skip access control checks.

PKGBUILD:
  Use PGO to optimize firefox. Uses Xvfb to run the profiling build of firefox.

firefox.sh:
  Adjust path.

mozconfig:
  Use PGO.
  Switch to unofficial branding. This changes name from Minefield (trunk build) to Gran Paradiso, which is the codename for firefox 3.0.
  Define some extra variable to make PGO work

    Use a launcher script instead of symlink. Fixes FS#10737. Use srcdir and pkgdir variables, add some || return 1 checks
