Bug#765421: jmapviewer/josm issue

[Felix Natter]

Dear GIS maintainers,

since we removed bing_maps.png from jmapviewer in the Debian package,
jmapviewer does not work with bing sat images in JOSM:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=765421

If you agree with this patch, then I can prepare an updated package
(including the patch) tomorrow and hopefully it will make it in time
for jessie.

Thanks and Best Regards,
