Use a more specific selector when checking for flash messages in lightbox

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.).

Extended maximum record_id length to 255.

- Empty advanced searches no longer revert to basic status.
- Resolves VUFIND-1154.

- Allows better follow-up for bulk actions.
- Reduces odds of strange behavior caused by unexpected user actions.

Consistency check for citations string

Don't try to check save statuses if the user is not logged in.
