Set Cookie-Path for OTRS cookies.

Setting the path for a cookie restricts its use to the given path. This
provides some extra security, other tools running on the same host but
using a different path can no longer access OTRS's cookies.
Because often OTRS is deployed on one host that does nothing but OTRS,
the extra security is limited, but still I feel we should use this
option.

See:
  - http://en.wikipedia.org/wiki/HTTP_cookie#Domain_and_Path
  - http://tools.ietf.org/html/rfc6265#section-5.2.4
Refactored mail backends.

We now use Net::SSLGlue::POP3 and Net::SSLGlue::SMTP which allow
us to use the same base modules for the SSLified backends as for
the 'plain' backends.

Therefore we drop the following modules:

 - Net::SMTP::SSL
 - Net::SMTP::TLS::ButMaintained
 - Mail::POP3Client
 - Net::POP3::SSLWrapper

Because we now use similar mail libraries for the connections, we can
use much less code; and we use 'use base' to derive the content of
the SMTP, IMAP, and POP3 backends in the SSLified versions.

Another benefit of using the Net::SSLGlue modules is that we can force
SSL certificate verification to 'off' - or we can pass verification
options to IO::Socket::SSL if we want to do this in the future.
Passing full options to IO::Socket::SSL was previously not possible
with all mail modules.
