References #2278: Improvements to login page for better extensions

Implemented a custom event before-login that is sent to the <form> element on the login page just before it is about to be submitted. Extensions may register for this event and may call event.preventDefault() to prevent the submission. A new method Login.submitLoginForm() can be called to submit the form without any more questions.
