CMS-2624 Content Form - Automatically set focus to display-name input when no display-name-script is available
Introduced WizardPanel.initWizardPanel which is called after wizard have been added to and shown in container intialFocus

Introduced methods preRenderNew, postRenderNew and postRenderExisting in WizardPanel

Added callback functions for methods: preRenderNew, renderNew, postRenderNew, renderExisting, postRenderExisting and setPersistedItem to ensure operations are done in order and not simultaneously

Introduced Element.onElementAddedToParent
Renamed method Element.showCallback to onElementShown
Fixed Element.reRender two what I believe is correct: first render innermost child, then self and also go infinite levels.
