nginx-0.3.13-RELEASE import

    *) Feature: the IMAP/POP3 proxy supports STARTTLS and STLS.

    *) Bugfix: the IMAP/POP3 proxy did not work with the select, poll, and
       /dev/poll methods.

    *) Bugfix: in SSI handling.

    *) Bugfix: now Solaris sendfilev() is not used to transfer the client
       request body to FastCGI-server via the unix domain socket.

    *) Bugfix: the "auth_basic" directive did not disable the
       authorization; the bug had appeared in 0.3.11.
