Adding a new constraint q_maxDownward2 and modifying q_rampDownLimit. A small change to v_reserve.up to make it work with consumption units as well.

q_maxDownward2: similar to q_maxUpward2 but for v_gen and downward online+offline reserve provision

q_rampDownLimit: do not consider offline reserve provision
