Appdata coverage update

[Ryan Lerch]

Just a quick update on the current coverage status for appdata in Fedora 
21. We are currently sitting at 36.9% [1] of applications that have an 
appdata file with a description.

However, we do have a bunch of appdata files that have been created in 
seperate branches that have not been merged yet (just waiting for a few 
more in the list of games we are targeting [2]), that should get this 
number up near 47% coverage in the next week or so.

cheers,
