Viewdeck now always stays open after presenting a modal controller.

This was a problem with using a navigation controller and viewdeck in integrated navigation mode.

Fixes #253.
Amended Multiviewdeck example to test issue #253.

Set top viewdeckcontroller to use integrated navigation mode.
Added `IIViewDeckAllViewsPanning` panning mode to allow panning in the full view deck.

Aka, you can start the gesture over a side controller when the center view is open.

Fixes #244.
Disable userinteraction while center is animating (open, close)

Fixes #226.
Fixed possible UIHierarchyInconsistency problem.

fixed bug with shouldCloseViewSide:animated: delegate check

Corrected issue with the delegate check for

and so the delegate respondsToSelector: check was always failing.
