[desktop-switcher] use Apply/Cancel/OK as per GNOME HIG

[Luca Ferretti]

As per http://library.gnome.org/devel/hig-book/stable/windows-utility.html.en#windows-explicit-apply

Or at least change the Apply button to OK

PS really, can't we make it an "instant apply window"?

[Neil J. Patel (njpatel)]

Heh, never noticed that one :-).

I don't think we should make it instant apply as it's a major change, but Apply/Cancel/Okay is definitely a good idea.

[Luca Ferretti (elle.uca)]

Don't forget this note about Cancel button:

"Note: this must undo the effects of all applications of the Apply since the window was opened, not just the most recent one."

This bug has been moved to Ubuntu distribution.
