David Goodwin 8a1f9a11af CSRF protection - support multiple tokens (#985)
possible fix for https://github.com/postfixadmin/postfixadmin/issues/967

CSRF Token changes : rather than have one PFA_Token value in $_SESSION, store a list of them, where each value has a time stamp it was issued on. The aim is to allow the user to have multiple browser tabs open at once - and not have the last tab that loaded trample on others. Tokens expire after 1 hour.

Adds a Smarty helper function `{CSRF_Token}` which will output `<input type=hidden name=CSRF_Token value=asdf123>` or `{CSRF_Token type=url}` which outputs a literal string like 'asdf123' suitable for placing in a URL.

Adds a PHP exception handler in public/common.php, which could be used to display a more friendly error message/response (but at the moment is fairly minimal).

Removes most uses of `die()` within the codebase, and instead moves to throw an exception
