* Added ability for public to submit a ticket via the web if they aren't logged in
* Added ability for public to view ticket via web using ticket ID & e-mail address
* Added public ticket URL to e-mails
* Added manager to FollowUp class to
options that are being used, allowing users to add or remove more options
rather than just display the lot on screen.
* Break out filtering and row hover into separate javascript files (hover
is used in the ticket list & dashboard - same code was used in both
places. Anti-DRY)
