Bug#657395: cinnamon needs to build depend on gnome-common

[Gregor Jasny <gjasny@googlemail.com>]

Hello Nicolas,

I tried to compile your package on my unclean desktop system. There I
catched the following error:

   dh_testdir
   debian/rules override_dh_autoreconf
make[1]: Entering directory `/home/gjasny/src/debian/cinnamon-1.4+up3+repack'
dh_autoreconf --as-needed ./autogen.sh
You need to install gnome-common from GNOME Git (or from
your OS vendor's package manager).
dh_autoreconf: ./autogen.sh returned exit code 1
make[1]: *** [override_dh_autoreconf] Error 2
make[1]: Leaving directory `/home/gjasny/src/debian/cinnamon-1.4+up3+repack'

After I installed gnome-common, everything built as expected.

Thanks,
Gregor
