Is there a way to "Clear all contents/delete all transactions" for a fresh start?

ATM we initialize the OSX application object and start the CFRunLoop in gnc_main_window_show_all_windows(). We'd need to split that so that we initialize it in inner_main() and register a handler for the g_signal "NSApplicationOpenFile". The hard part is dealing with the race between opening the default file and handling the signal.
