Reinstate vote actor support

[nickbabcock]

In #185 I deleted code (shown below) that fell back on the class hierarchy described in the replay instead of the ones we hardcode. Turns out, when running a regression test against the main replay corpus of 200k replays files -- 2 replays depended on this fallback being present. I've hard coded the missing vote actor, but the main thing is adding the regression replay to the codebase so this doesn't happen again in the future.

	// Sometimes our hierarchy set up in build.rs isn't perfect so if we don't find a
	// parent and a parent cache id is set, try and find this parent id and carry down
	// their props.
	if !had_parent && cache.parent_id != 0 {
	if let Some(parent) = body
	.net_cache
	.iter()
	.find(|x| x.cache_id == cache.parent_id)
	{
	if let Some(parent_attrs) = object_ind_attrs.get(&ObjectId(parent.object_ind)) {
	all_props.extend(parent_attrs.iter());
	}
	}
	}
