[Cin] small fix for qt vs mov format option

[Andrew Randrianasulu]

I basically hacked fileffmpeg.C so it will allow me to choose mov flags for (cin-specific) qt 'format'. Of course one can rename all those qt profiles too...

int FFOptionsFormatView::handle_event()
{
	Asset *asset = fmt_config->asset;
	char *format_name = asset->fformat;
	char *replace_name = "mov";
	if (!strcmp(format_name, "qt"))
		format_name = replace_name; // fixup
	avformat_free_context(fmt_ctx);  fmt_ctx = 0;
	int ret = avformat_alloc_output_context2(&fmt_ctx, 0, format_name, 0);
	if( ret || !fmt_ctx ) {
		eprintf(_("no format named: %s"), format_name);
		ret = 1;
	}
	if( !ret )
		fmt_config->start(fmt_ctx);
	return 1;
}

basically just three lines. But I have other changes  for this file so diff will be not clean.

I killed additional lines, but then linecount can be wrong ...
