Fixing install bug
Fixing settings UI

This change updates the UI for 2.4 and fixes #20
1.4.3 Release notes
Version bump
Added notes about Remote IP address field name
Fix #21 - Use defaults setttings when they exists

Only use the author information when no setting can be found.

Use default if not. This fix a bug that's been there for sooo long.
Thanks @michael-e.
Extracted the logic for getting the default email gateway settings
Added a page alert when unband is on but no email gateway exists
Insure we unband via email won't work if disabled

This change should fix #22, particullarly the change made to line 269
of class.ADF.php that fix the if statement, which will prevent leaking
the unband link.

This change also fixes some typos and add an extra step to the sendEmail
function that will abort if unban is not active.
