Modernize the web interface

[dajones70]

Feature request:

• Bootstrap
• Tooltip long fields (i.e. From, Subject) in the status.php
• Tooltip input fields in the reports.php
• Allow for the detail.php link to open in a new tab as global option in conf.php

Existing bug not fixed:

• Session timeout redirect to the login page instead of giving a token error

@dajones70 Great feature requests. As for the session timeout, I haven't heard back from you on your message on PR #1111 . I will be more than happy to help troubleshoot this for the existing version.
