Log Message:	Port --enable-standalone-gui support to SheepShaver Others changes include: - Factor out STR_SIG_INSTALL_ERR messages - Process command line arguments early (prior to calling PrefsInit()) - GUI: set start_clicked only if the "Start" button was clicked - GUI: save changes to the "Input" pane when the "Start" button was clicked
