Fixed a bug the a hyper-link included the username/password input fields.
Use submitLoginFormIntoDivAndReload to replace submitLoginFormIntoDiv js function.
redirect to the registry form following successful login - but allow an override in case we only want to render the success and stay there (ajax call from main sanparks page).
Change sanparks skin to log in with browser session instead of metacat client session so session can be validated on other pages.
