Everything looks good. 👍

[martinpovolny]

@bmclaughlin : you have some IEs and stuff, can you, please, review this one?

[bmclaughlin]

Will do @martinpovolny.

[Fryguy]

Code-wise pretty straightforward, so when @bmclaughlin comes back with a 👍, we can merge

[bmclaughlin]

👍 IE11
👍 IE10
👎 IE9, throws the following error:
SCRIPT5009: 'ArrayBuffer' is undefined spicearraybuffer.self.js?body=1, line 54 character 1

[martinpovolny]

@bmclaughlin : I expect several issues in IE9 or earlier that I do not try to address in this PR.

[bmclaughlin]

@martinpovolny then I'd say this is good to go.

Sorry @bmclaughlin @martinpovolny, sounds like fun 😭

[bmclaughlin]

@martinpovolny, looks like you're off the hook for the IE9 error, although the error in master is much more entertaining:
Line: 51 Error: WebSocket unavailable. You need to use a different browser.
