Merge lp://qastaging/~jassmith/do/docky-cursor-polling into lp://qastaging/do/0.8

AbstractMenuButtonArgs:
 Catalog.GetString (GLib.Markup.EscapeText (description)) -- think about what this means, it's wrong

Why so many new lines in UnregisterEvents?

The if/else in ResetCursorTimer should be changed to not repeat the Timeout.Add.

Wrap your comments to 80 cols.

At cursorMoveWarrantsDraw, you use unneeded ( ).

OnLeaveNotifyEvent has some very long lines.

HandleDragMotion has very long lines.

DockItemProvider Un/RegisterEvents has some extra newlines. OnWindowClosed/Opened has funky indentation.

Why is DockWindow Vanish doing so much ungrab work? Can't this go in Controller? Why is it Ungrabbing itself?

Why is ItemPositionProvider returning the DockItems of its ItemProvider, and not just exposing its ItemProvider? Why is it exposing a List instead of an IEnumerable, or ICollection?

IconZoomedPosition, IconUnzoomedPosition -- wrap your comments to 80col.

In DockPreferences, let the compiler add the <T> for you after Get and Set (you only need Set, not Set<bool>).

You Ungrab in Bezel -- seems like a good place, better than in the controller. Can you PresentWindow in Bezel too?

Fix these things, then merge.
