Bugfix bonus_increase

This value was not included in the ranges of get_calculators(),
and therefore was being ignored.
It likely does not affect the outcomes of most tests,
but likely is involved in mitigation/damage or mitigation/heal
calculations.

Also may have determined the correct paramater format for
sqp()'s maxiter.  It seems to need to be matrix.
Looking at the sqp source code, there seems to be logic
error here (in my mind), but this seems to work "better" at least.
Minor cleanups in get_h()

Unclear if constructing matrices and then calling sum()
over the matrix is clearer (or faster) than infix '+' notation.

Going with the latter for the moment.
