Create IQmol.appdata.xml

Please consider including this (or writing your own) AppData file for linux distributions. It allows applications to be presented in a nice, consistent way in GNOME and KDE software centers. This file should be placed in /usr/share/appdata, just like .desktop files are placed in /usr/share/applications. AppData files contain a description of each application, links to 16:9 screenshots and other information (e.g. homepage, project license etc.).

You can read about the specifics of AppData here:

http://www.freedesktop.org/software/appstream/docs/chap-Quickstart.html

I took the liberty of taking a few 16:9 screenshots myself, as you can see in the xml. You could use your own and host them on IQmol's project page. Just make sure they are the right ratio and that the file passes validation (I could do that for you).

Please let me know, so that I may update the list of supported applications in Fedora.

Thanks for your great work
