cleanup: replace Q_FOREACH and foreach by range base for

Browse source 
Q_FOREACH and foreach are anachronisms.

Range based for may cause a performance regression: it can
lead to a copy of shared containers (one reason why Qt's
COW containers are broken). However, as long as there is no
user noticeable delay, there is no point in analyzing each case.
And also no point in slapping an 'asConst' on every container
that is looped over.
