Experimentally adding an option for automatically erasing an

hypothesis when using it in apply or rewrite (prefix ">",
undocumented), and a modifier to explicitly keep it in induction or
destruct (prefix "!", reminiscent of non-linerarity).

Also added undocumented option "Set Default Clearing Used Hypotheses"
which makes apply and rewrite default to erasing the hypothesis they
use (if ever their argument is indeed an hypothesis of the context).
