Bug 10848 - [QA Followup] Add missing branch option and fix pattern for copyrightdate

- HTML5 input pattern for copyrightdate was not taking into an account
the database field type, which is smallint(5)
- added title="..." for the year field so the acceptable date format
should be displayed as a hint/tooltip in the browser
- added an missing option for configuring branch/library as mandatory
