gtk2-metatheme-industrial-0.6.5-bp156.3.1

- Modernize spec-file by calling spec-cleaner

- Change gtk2-engines Requires to gtk2-engine-industrial and
  gtk2-theme-industrial Requires, now that gtk2-engines has split
  packages (see bnc#706929).
- Add Supplements for gtk2-engine-industrial and
  gtk2-theme-industrial since it makes sense to have the metatheme
  installed in that case.

- add automake as buildrequire to avoid implicit dependency

- Replace gtk2-theme-openSUSE with gtk2-metatheme-gilouche.

- Industrial icon theme renamed to Gilouche and moved to
  gtk2-theme-openSUSE (bnc#369276#c9).

- Added latest Industrial icon theme (bnc#369276).

- Split the Industrial metatheme out of gnome-themes and
  ximian-artwork (bnc#380955).
