3c6da0ffdc Clause buffer must be fitered when popping 
Indeed imagine the following case:
"push; assume [c]; pop; push; solve"
since c has user-level 1, in the current state, it would
have been wrongfully added to the solver state when solve
is run.

9dadb67fc9 [bugfix] Sort false atoms by levels in new clauses 
When a new clauses is added and it is a conflict (i.e all atoms
are false), one must take care of which literals to watch.
In order to work, the watched literals must be those with the higher
decision levels, or else the watched literals might not react when
needed. This is fixed by sorting the literals in decreasing order of
decision level when adding a new clause which happens to be false in the
current trail.

9be4c66911 [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.
