Added code to get rid of duplicate rewriting rules.

A rule is a duplicate of another rule when their types are alpha convertible.
Eliminating duplicates speed up the tactic (but it slows down the operation
of addition of a new rule that is also performed every time subst_mps is applied
to the module).
