create appdata file

[GoogleCodeExporter]

I'm not sure how widely this would be used by package managers and software 
installation centers, but adding an appdata file for pychess might be useful: 
http://people.freedesktop.org/~hughsient/appdata/

From that web-page:
"Applications wishing to have long descriptions, screenshots and other useful 
things are required to ship one or more files in 
/usr/share/appdata/%{id}.appdata.xml. The %{id} is the same name as the 
installed .desktop file for the application. This file will contain something 
like this:

<?xml version="1.0" encoding="UTF-8"?>
<application>
 <id type="desktop">gnome-power-statistics.desktop</id>
 <licence>CC0</licence>
 <name>Power Statistics</name>
 <summary>Observe power management</summary>
 <description>
  <p>
   Power Statistics is a program used to view historical and current battery
   information and will show programs running on your computer using power.
  </p>
  <p>Example list:</p>
  <ul>
   <li>First item</li>
   <li>Second item</li>
  </ul>
  <p>
  You probably only need to install this application if you are having problems
  with your laptop battery, or are trying to work out what programs are using
  significant amounts of power.

Fedora 20 ships GNOME Software (which uses appdata files) by default:
