    Register and init in VuFind.

Added a fallback for creating CustomEvent on Internet Explorer and switched from direct access of dataset to jQuery for IE support.

Use a more specific selector when checking for flash messages in lightbox so that other markup using the classes doesn't confuse lightbox. Also always use jQuery selectors to find the flash messages to be more tolerant of markup changes (e.g. whitespace, class ordering etc.).

Lightbox: Added error handling in ajax call and button handling also for lightbox forms outside lightbox. Added also the possibility to ignore a form inside lightbox or a button inside lightbox form.

Include details about the url's in the VuFind.lightbox.login event so that different action can be initiated based on the values.

Don't use window.location.reload() to refresh the page because it would warn about any POST parameters (e.g. login right after changing language).

Added a login event to the lightbox to enable custom actions when a login is performed in a lightbox.

Isolate success messages from the html in lightbox first before trying to deframe it for success messages to work even if the isolation would not be successful.

Improved the clicked submit button detection to work on all platforms and cases where the form has multiple submit buttons.

- Rewrote Javascript to make better use of server-side logic
- Eliminated many server-side special cases specific to lightbox handling
- Adjusted test suite to accommodate improvements
