Description

This fixes alot of compiler warnings by going for some low-hanging fruit like includes with lots of warnings or smaller changes leading to a cascade of warnings being removed. The change in pserror.h alone removes more than one thousand warnings. For MSVC this gets down from 2440 to 840 warnings.
