Fixes #264

we continue to use the duplicating version of eliminate_if_term for
atomic formulas but we replace if-then-else with epsilon in Tlet and Tcase

This also adds an mli file for apply.

not updated:
- stdlib/array - the proof is broken
- ring_decision/ - not replayed, proof broken
- in_progress/, util/, prover/bench/ - not replayed

new file for issue 166

It is possible to append an arbitary number of quote symbols
at the end of an prefix/infix/mixfix operator:

            applied form      standalone form

              -' 42               (-'_)
              x +' y              (+')
              a[0]' <- 1          ([]'<-)

Pretty-printing will use the quote symbols for disambiguation.

The derived symbols can be produced by Why3 by appending
a suffix of the form "_toto" or "'toto". These symbols can
be parsed/printed as "(+)_toto" or "(+)'toto", respectively.

Corrected typo in Pretty.ml

For the previous behaviour (no import), write "use/clone T as T".

This shortens the most used "use/clone import" to simply "use/clone".

Clone "with axiom ." or "with goal ." to change the default
("with lemma ." is also accepted, just in case).

As a side effect, this also modifies reflection.ml accordingly.
