get rid of some foreach and Q_FOREACH constructs

Browse source 
See https://www.kdab.com/goodbye-q_foreach/

This is reduced to the places where the container is const or can be made const
without the need to always introduce an extra variable. Sadly qAsConst (Qt 5.7)
and std::as_const (C++17) are not available in all supported setups.

Also do some minor cleanups along the way.
