Windows start menu item support for kickoff, part 2

[Fabian Aichele]

Hello!

Summing up the various responses received after submitting my small addition 
to kickoff under Windows, I'd like to ask for some further advice on how to 
better integrate this feature into KDE.

Keeping this kickoff-specific clearly is not an optimal solution, and I 
hadn't intended to leave it this way. My problem is that I don't know enough 
about the internals of the KDE core to devise the best approach myself.
ksycoca and vfolder_menu are definitely good candidates for further 
modifications; but apart from that, I wouldn't know where to look as well, 
for example when it comes to the "dynamic" conversion of Windows' file 
extension schema to KDE's .desktop files.

If anyone is willing to give further advice, or even help me with the more 
advanced features (like icon extraction), let me know!

Regards,
Fabian Aichele
