Gets the options there were passed to g_application_command_line().
If you did not override local_command_line() then these are the same
options that were parsed according to the #GOptionEntrys added to the
application with g_application_add_main_option_entries() and possibly
modified from your GApplication::handle-local-options handler.
If no options were sent then an empty dictionary is returned so that
you don't need to check for %NULL.
