OnLoad Method (WebTab)

Ensure templates. Note: that is required to support controls which rely on processing Page.Load/Complete event. For example, WebDatePicker can create shared calendar only if it gets Page.LoadComplete. But default logic of dot-net creates child control within OnPreRender, which is too late for WebDatePicker.
