rss-glx-0.9.1-bp150.2.3

- Fix license
- Cleanup BuildRequires

- Drop dependency on kdebase4-workspace

- fix build with ImageMagick 7
  + rss-glx-ImageMagick7.patch

- fix boo#901450
  * soft-link binaries from /usr/bin to %%{_libdir}/xscreensaver
- use --program-prefix=rss-glx to distinguish from those
  screensavers shipped by xscreensaver itself.

- add pkgconfig(glu) as explicit buildrequire

- add libtool as buildrequire to avoid implicit dependency

- change the license to GPL-2.0 as that's what COPYING says and
  I found at least one file without "or later"

- cleanup spec file

- Fix build with no-add-needed, just by not using static linking
- Fix lack of optflags due to broken configure script

- update to 0.9.1:
  * added port of Pixel City
  * replaced methods deprecated by ImageMagick
- fix build on < 11.2 by defining _kde4_servicesdir if not already defined

- initial package
