510a8aaa34 [bugfix] Clause level now computed at creation 
Apart from new assumptions, clause level can always
be computed from the histoy of the clause, so it is
better to do it in Solver_types when creating clauses.
Aditionally, it seems there was an error in the manual
computing of clause level somewhere, this fixes the bug.

2613926ab1 First changes for better persistent proofs 
This commit ensures that clauses now contain
all necessary information to construct the proof
graph (without relying on propagation reasons).
