Bug#864281: orage clock panel plugin background transparency doesn't work

[Klaumi Klingsporn <klaumikli@gmx.de>]

Dear maintainers,

Would be nice, if you applied the ubuntu patch to the
debian-package as well.

I built a personal debian package with this patch
(http://apt.klaumikli.de/testing) and it works just fine.

I attach the patch again as it is needed for debian/patches.

BTW: While building my personal package I recognized that
in your package the dbus-files from upstream were not
installed. To make this happen, there has to be a new line
in debian/orage.install:
usr/share/dbus-1/services
(but this should actually be a seperate bug-report)

Thanks for maintaining the orage package!

Klaumi
