GIMP's Start menu entry on Windows is inspecific
Currently, GIMP's Start menu entry on Windows says "GIMP 2", which apparently contributes to bug reports stating "I'm using GIMP 2, I have this problem, help", which, in return, adds another step in communication with users ("What version exactly is that? Use Help > About").
It doesn't look like all apps for Windows show specific version in the Start menu, but Microsoft does it for Microsoft Office, so why can't we?
Let's show both major, minor, and micro versions.
