Formatting & Typo fixes

Noticed that some of the botkit headers weren't aligned, so I fixed that.

I also added shield.io badges for the most relevant information (npm version, dependency currentness

The ws vulnerability is described here and should be patched, but I'll leave that to y'all.

Those gifs 🙌

Would it make sense to also remove tap-spec and tape from the package.json in this PR? It looks like they're leftover from how the tests used to run, and not being used anymore.

Good call! Also looks like node-env-file isn't being used either? The only place it shows up in the repo is in package.json itself. I'll pull all three.

Also found these style errors after running npm test, fixed.

@anonrig ah, sorry. Fixed!

[anonrig]

Security comes first. Can you update ws and before updating read the changelog and notify us if anything is broken?

Thank you.

[xavdid]

@anonrig the commit was a small one and after updating, all the tests and some tire-kicking passed.

Thank you!
