WL-2186 If the site title has already been defined, then don't show it in the new site form.
There is no need to ask twice.
WL-2196 adjusted the javascript on the form validation to renable form submission if the title field is hidden.
WL-2186 adjusted the form processing to save the state title if it is defined or to take the form value in its absence. Some additional minor fixes.
WL-2186 DRY out code to handle a change to the site title.
