Gets the options there were passed to command_line.
If you did not override local_command_line then these are the same options that were parsed according to the
OptionEntrys added to the application with
add_main_option_entries and possibly modified from your
GApplication:GApplicationCommandLine:handle-local-optionss handler.
If no options were sent then an empty dictionary is returned so that you don't need to check for null.
