[bugfix] Fix typo following doublon elimination
...
Following a bugfix for doublon elimination, doublons are now eliminated
in add_clause, and as such, in case no simplification is made, the
clause without doublons should be used (and not init). This was a typo
missed during the refactoring of doublon elimination.

Add generativity of Dimacs functor
...
Since the dimacs functor has an internal state (relating to the output
in iCNF format), it is desirable to have a generative functor, inc as
esomeone wants to output select parts of a problem to two distinct iCNF
files).

[bugfix] Eliminate duplicates in input clauses

When adding clauses that conatins duplicates, the checking

[bugfix?] Avoid forgetting theory conflict clauses
...
When theory raises a conflict, it is analysed, and the backtracck clause
that result is added to the solver, however, I didn't find yet a
satisfying answer as to wether the original clause is implied (or not)
by this backtrack clause, so in order not to lose information, we also
add the original conflict clause when it comes from the theory (because
if not, then it comes from a conflict detected during propgation, so the
conflict clause is actually already attached).
