Change ignore_sighup default to False

This means child processes will no longer ignore SIGHUP by default.

Also pulled out a 'backwards incompatible changes' section of the
release notes to make it clearer what has changed.

 * It is now possible to call :meth:`~.wait` multiple times, or after a process
   is already determined to be terminated without raising an exception
   (:ghpull:`211`).
-* Deprecated ``pexpect.screen`` and ``pexpect.ANSI``. Please use other packages
-  such as `pyte <https://pypi.python.org/pypi/pyte>`__ to emulate a terminal.
-* Removed the independent top-level modules (``pxssh fdpexpect FSM screen ANSI``)
-  which were installed alongside Pexpect. These were moved into the Pexpect
-  package in 3.0, but the old names were left as aliases.
 * Fix regression that prevented executable, but unreadable files from
   being found when not specified by absolute path -- such as
   /usr/bin/sudo (:ghissue:`104`).
 * Fixed regression when executing pexpect with some prior releases of
   the multiprocessing module where stdin has been closed (:ghissue:`86`).
