Extension:Wizard for Extjs 1.x and 2.0

This has been requested several times by multiple people. NOTE: Although it is not currently planned as a separate component in Ext 2.0, building a wizard should be fairly trivial once 2.0 arrives since it will have a built-in card layout. Extending that into a wizard component should be pretty easy, so you should probably wait until then before starting too far down this path.

Possible Requirements

• Standard (optionally) bottom button bar: Previous, Next, Finish, Cancel
• Render in dialog or in a page (div / (tab)panel)
• Steps can hold Ext.Form instance(s)
• Optionally lazy render steps (load on demand)
• Events from each button (onprevious, onnext, etc.), events can be canceled (to allow checking (Ext.Form.)IsValid() )
• (Optionally) Show a list with wizard steps with current one highlighted (like in most application setup wizards)
