About "apply in":
- Added "simple apply in" (cf wish 1917) + conversion and descent
under conjunction + contraction of useless beta-redex in "apply in"
+ support for open terms.
- Did not solve the "problem" that "apply in" generates a let-in which
is type-checked using a kernel conversion in the opposite side of what
the proof indicated (hence leading to a potential unexpected penalty
at Qed time).
- When applyng a sequence of lemmas, it would have been nice to allow
temporary evars as intermediate steps but this was too long to implement.
Smoother API in tactics.mli for assert_by/assert_as/pose_proof.
