- remove two registry path deletions that were never performed since the paths do not exist
- remove registry key that stores the main window parameters (size and position) when the option to remove also the user settings is on (because this affects all FreeCAD installations)
- also change a name to uppercase (does not matter but Win 10 uses uppercase, so we should do the same to avoid confusions)
there is no need to have 2 plugins doing the same
moreover FindProc does no longer work with recent Windows 10 versions, so it must be removed anyway
- configure.nsh: small code optimization
- Settings.nsh: update year
- fix bug that registry uninstaller settings of the previous version are not replaced when installing new version of the same series
- avoid explicit calls of the name "FreeCAD"
- update example code and description to MSVC 2017 and FreeCAD 0.19git
