Added new signal interface using boost::signals2 signalParamChanged.
Exposed to Python as ParameterGrpPy.AttachManager() to monitor changes
to all parameters, sub groups under the referring group.
Added new attribute for ParameterGrp(Py) to query the Parent and Manager
of the referring group.
* ignore -Wfree-nonheap-object for generated code

Qt ignores shortcut of actions in invisible toolbar, but not for actions
in a hidden menu action of menu bar, which is likely a Qt bug. The
desired behavior should be that of toolbar actions, so that actions
belong to different workbenches can have the same shortcut without
conflict.
This commit works around this inconsistency by ensuring only the active
actions are added in menu bar. In addition, all active actions will be
added to a zero sized child widget of the main window, which ensures the
shortcuts of these actions being active regardless whether the action is
in toolbar or menu bar, visible or not.
Removes the BUILD_QT5 flag and adds a new FREECAD_QT_VERSION option,
which can be set to either "Auto" (default), 5, or 6. Auto detects which
version of Qt is installed on the system and chooses it. If both version
are installed, Qt5 is used.
Note that this DOES NOT implement compiling against Qt6, it only adds
the necessary cMake infrastructure to begin work on the source code
changes that will be required.
This undoes a small part of commit 9ec0bcdcf2,
which seems a bit too agressive. Without the cmath header the build fails
using Apple clang version 11.0.0 (clang-1100.0.33.17) on Mojave with the
following error:
.../FreeCAD-git/src/Base/UnitsSchemaInternal.cpp:39:24: error: call to 'abs' is ambiguous
