I'm manually creating the metadata on my machine until we get all the
bits we need to do this on koji after each build, but the installed
appdata should be used in preference to the cached metadata there.

Install them to /usr/share/appdata/ -- i've not tested this with
Fedora 20, but I know it works if you're using the rawhide package.

It's not mandatory, but highly reccomended. See

How large is the actual screenshot in pixels? If you run
"appdata-validate -v foo.appdata.xml" it'll tell you the parameters
it's using for validation.
