CLI: Add new option --file-query to auto answer QFileDialog

QFileDialog.getExistingDirectory and QFileDialog.getOpenFileName
can be called from scipt. If command line interface is used, user must
type the correct directory or file name from command line during install.
With --file-query option user can give the values when running the
installer or maintenancetool with syntax --file-query
filedialogId=C:/temp,filedialogId2=C:/temp/file.txt.
