Patch for Close All, Minimize All, Restore All for Grouped tasklists

[Srinivasa Ragavan <sragavan novell com>]

Hi,

I have attached a patch, that will provide a button to close, minimize,
restore group of same tasks in libWNCK:tasklist.

Review it and provide me comments for improvisation.
I have also attached a screen shot of how it will look like.

Thanks
Srini.
