Help, Ok, Cancel KStandardGuiItems

[Allen Winter]

Howdy,

I noticed that the Help ,Ok and Cancel buttons in KDialogs
don't have tooltips or whatsthis. (Help has a tooltip, but no whatsthis).

This is due to those settings missing in KStandardGuiItems::ok(), et.al.

Is there a good reason for this?  Should I add the tooltips/whatthis
to the KStandardGuiItems? Or not? Or maybe add them into
the KDialog class directly?
