create an AppData file for JOSM

[richard@…]

Please consider writing and installing an AppData file with the application description and some screenshots, else JOSM Map Editor looks really bad in the GNOME and KDE Software Centers. We'd love to showcase more applications, but without the extra data file we can't. See ​http://people.freedesktop.org/~hughsient/appdata/ for details; thanks!

We first need to close #3123 :)

Richard: is it enough to have created this file in our repository or do we need to do something else? Were can we see if you're using our file?

Two enhancements:

• .desktop need translation of strings
• a vector graphic is preferred as icon

You need to install the file into /usr/share/appdata -- and then when you next release a tarball and it gets build for the distro it all magically works. You can see what the output is in Fedora 21 by visiting ​https://alt.fedoraproject.org/pub/alt/screenshots/f21/status.html#josm.desktop -- other distros may take longer to pick up and build the file.

Hi! Fedora picked up the AppData file today, thanks. One small error is stopping it working:

/usr/share/appdata/josm.appdata.xml license 'CC BY-SA-3.0' invalid

This needs to be "CC-BY-SA-3.0", i.e. with all dashes to match the SPDX value found here ​http://spdx.org/licenses/

Thanks!
