Corrected and renamed XDG desktop entry and Appstream metainfo XML.

Adjusted based on feedback from the Appstream validator (appstreamcli
validate-tree).  Changed metainfo ID and file names to use reverse DNS
notation.  Added categories, homepage URL and icon reference to the
metainfo file.  Changed URLs to SSL secured variants.

This replaces the changes proposed in pull requests MaartenBaert#993 and MaartenBaert#994.
