extensions: show traceback on load failure if --traceback flag is set Before this patch, there was no handy way to investigate the reason why extension couldn't be loaded. If ui.debug is set, tracebacks of both "hgext.foo" and "foo" are displayed because the first ImportError could occur at very deep dependency module.
