gtk2-engines-2.20.2-bp160.1.1

- Drop baselibs.conf: the -32bit packages are no longer needed and
  have not been part of Tumbleweed for a while already (build for
  i586 only enabled in LegacyX86).

- Use %autosetup instead of %setup/%patch.
- Fix baselibs.conf: reference correct name of hcengine.

- Spec-cleanup using format_spec_file service.

- Manually remove translations in %install and drop lang
  subpackage: the translations are useless at runtime, since they
  are integrated in the xml files.
- Add Obsoletes for gtk-engines-lang to main subpackage, for smooth
  upgrades.

- Split gtk2-engines package in subpackages for each engine and
  theme: gtk2-engine-{engine_name} and gtk2-theme-{theme_name}, for
  clearlooks, crux, glide, hcengine, industrial, mist, redmond95,
  thinice. Fix bnc#706929.
- Add Requires for all new subpackages to gtk2-engines: it is now a
  metapackage used to install all engines and themes.
- Add README.openSUSE to gtk2-engines to explain that this is a
  metapackage.
- Remove fdupes BuildRequires and call to %fdupes since it can't be
  useful anymore with split packages.

- Add gtk-engines-glib.patch: Fix build with newer glib, where only
  glib.h can be #include'd.

- Fixed typo in description of gtk2-engines.spec

- Use --whatprovides to find the version of gtk2 since we split
  gtk2 according to the shared library packaging policy, and there
  is no gtk2 package anymore.

- Update to version 2.20.2:
  + Fix evolution ETree header in Clearlooks
  + Minor fixes in mist
  + Removed Xfce specific workaround from the clearlooks engine
    (bgo#616124)
  + Updated translations.

- Change lang package Requires to Recommends since it is not
  mandatory at runtime.
