Windows 7 specific icons for the tray

[ktlinux]

Could you please add the Windows 7 specific icons for the tray? I found someone did publish them separately here. I tried simply merging the contents of this to your theme but not all icons have changed.

Also there is one of the volume icons (not in yours) that has white background instead of transparent, but I kinda fixed it by editing the icon in GIMP (although there might still be some marks if you look really closely).
