Icon= directive in desktop entry should not have an extension

[WhyNotHugo]

The file /usr/share/applications/org.nongnu.lingot.desktop includes the line:

Icon=org.nongnu.lingot.svg

This should be only the name of the icon without the extension, e.g.:

Icon=org.nongnu.lingot

With the extensions, launchers (fuzzel in my case) won't properly find the icon (since they'll search for files where org.nongnu.lingot.svg is the base name without the extension).

Grepping /usr/share/applications confirms that no other desktop entry specifies an extension.

I was going to submit a patch, but it doesn't look like this file is included verbatim in the repository; it seems to be programmatically generated, but I couldn't figure out where/how.
