Update to fix issue #189: https://github.com/osTicket/osTicket-1.7/issues/189

Use the actual error message set in Staff::login instead of boring "Authentication Required";

* Change table name from ost_email_filter* to ost_filter*
* Add patch for target field.

 * Collapse Department into Staff tab.
 * Add a new 'Manage' tab - home for managing items, lists..etc.
 * Collapse Help Topics into Manage tab.
 * Move SLA and API from Settings to Manage tab.

This will help distinguish between the knowledgebase part which encompasses
FAQ's and canned responses, and the FAQ part which contains the articles
detailing frequently-asked-questions.

- Move access to it's own table.
- Refactor what department membership means in relation to group access

Add print options supports - staff can now print a ticket thread without internal notes + select paper size on the fly

And remove unnecessary parts of bootstrap.css
