"Professional CMake" book suggest the following:
"Targets should build successfully with or without compiler support for precompiled headers. It
should be considered an optimization, not a requirement. In particular, do not explicitly include a
precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
generated precompile header on the compiler command line instead. This is more portable across
the major compilers and is likely to be easier to maintain. It will also avoid warnings being
generated from certain code checking tools like iwyu (include what you use)."
Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
This adds dragging support for toolbars placed in custom toolbar areas.
It is achived by creating our own custom ToolBar class that handles
logic of providing custom gripper. This is required because Qt hides
gripper when toolbar is not direct child of the main window which cannot
be overriden. Custom class should allow us to create more capable
toolbars in the future so it should be great addition on its own.
