Cocoa Dialog Helpers: Refactor OK-Cancel buttons view

Browse Source 
Since virtually all the logic is shared between QNSColorPanelDelegate
and QNSFontPanelDelegate, we extract the added buttons and
layouting logic and move it into its own class. This requires
the two afore mentioned Objective C classes to satisfy the
QNSPanelDelegate protocol.
