Makes minlight additive rather than just bringing low levels up to the

treat local minlights in some strange ways, but in most cases the
behaviour should be identical.
Added missing help text for -anglescale|-anglesense parameters too.

Extend skip support to recognise the liquid skip texturenames the same as
metlslime's "newskip" utility. Add documentation and describe hint
surfaces (briefly) as well.
