• Added a new [enableBackLinks] directives which can be used to enable back links inside a wizard-completion-step. This makes it possible to exit an entered wizard-completion-step
• Added two new directives [wizardStep] and [wizardCompletionStep], which can be used as an alternative to the <wizard-step> and <wizard-completion-step> components to define a wizard step. These directives make it possible to move a wizard step to a new component, which can then be used inside a wizard component
