auth: Handle REQUEST_URI not being authoritative

'where 1' and 'where 1=1' gives me hives...

If _SERVER{REQUEST_URI} does not start with a leading slash, add one. This
will ensure that the redirect URL offered after a successful login will
be to an absolute url rather than an implied relative one.

email: Accept inline body with disposition params

Reviewed-By: Peter Rotich <peter@osticket.com>

A mail client may indicate a header parameter (such as Novell Groupwise,
which may add something like

Content-Disposition: inline; modification-time: "Thu ..."

) Previously, the system would not consider the content to be a candidate
for the email body, because it has parameters to the content-disposition
header.

This patch will still consider the part to be a candidate for the body if
the mime types match and no filename is found in the content-disposition
parameters.

email: Handle poorly encoded email headers

Reviewed-By: Peter Rotich <peter@osticket.com>

Handle cases where email headers contain unicode or high-ascii characters
and are not encoded according to RFC-2047. This patch handles a special case
where a detectable unicode character set is used, such as UTF-8. For
high-ascii characters in a character set other than iso-8859-1, the result
of this patch is undefined.

Fix filter issue where negative logic prevents matches

Reviewed-By: Peter Rotich <peter@osticket.com>

The quickList() method will attempt to ask the database to find filters that
might match the incoming ticket information. The idea is that MySQL is
likely faster than PHP. The problem is that it assumes positive logic is
being utilized.

This patch adds all filters with at least one rule with dn_contain
(does-not-contain) or not_equal (not-equal)

Fixes #834 (again)

Fix parsing issue in strtotime()

Reviewed-By: Peter Rotich <peter@osticket.com>

PHP can't discern the difference between d/m/Y and m/d/Y when just the date
is submitted to strtotime(). Unfortunately, strptime() is not available
until PHP 5.1.0. This patch forces datepickers to change their values to
YYYY-MM-DD upon submission to disambiguate parsing issues.

Better email headers for In-Reply-To and References

Make captcha text case-insensitive

Previous the options defined for the Mailer::send() function were confusing
when sending an In-Reply-To header

Previously, the References header emitted by the system for new thread
entry auto-responses and alerts included the message-id for which the email
was a reply in the `References` header. This patch corrects the issue by
placing the reply message-id in the In-Reply-To header, and constructs a
correct References header.

That is, if available, the References header received in the email that was
used to create the thread entry is appended to the message-id the email is
actually in reply to. This is the expected usage of the References header.
