Attachments aren't properly implemented

...

If only we handle this the right way from the start, we could only have 2 or 3 message type: "message" (with an array of attachments), "sticker" and "event". That way, it'll be nicer.

Oh, also there's "url" attachment too.

Yeah I wish we hadn't done this this way, but I don't think we can afford to just break the API. The fix I proposed should be enough for now. We can maybe keep a list of features/fix we want and make a v2.0 with breaking changes. @Schmavery what do you think?

Also it seems like the attach_type is "share" and not `"url" (on my end at least)

[blazeu]

Why not v1.0? We don't have that.

Sorry, I haven't checked it, but I've figured out how to send it tho. I might make a pull request soon.

I think the model that @blazeu described is a very good option. There are a number of other breaking changes I've been considering, so maybe we can work on putting together a list to release all at the same time.
