Added .editorconfig

Auto-configure editors for 2 space indention. There are a few more options we could set, see here for more:

I'm generally 👎 to adding these to repos, but would like to hear from others and what the thoughts are :)

[wesleytodd]

Thats fine, I can make this work for myself in other ways, I just looked for a more standard/common solution. The issue is that I default my editor to tabs, so every time I submit a PR I have to pour over it to make sure I got all the indentation correct. In this crazy world we live in where people think it is sane to use spaces ;), this is one way to ease it for tabs people.

PS. to make it obvious, I was joking about the tab/spaces thing. But I seriously just want my editor to fix these things for me.

EDIT: Also, on other projects I use standard to just auto-format. But the state of the express repo means I cannot do that, because it would introduce TONS of unintended changes.

I would normally be 👎, but this:

make me 👍, at least until we have everything following standard style :)

I'd go as far as saying implementing a linting tool would be better suited considering the inconsistencies within the app around code style. The linting could then take into account the aforementioned .editorconfig.

[dougwilson]

Yes, we are implementing StandardJS, but trying to balance implementing that with it causing a complete reformat of the code, pretty much invalidating any outstanding PRs :)

Well, I'm going to merge this PR for everyone, and I remove the trailing line exception from Markdown files (and fixed the markdown file with all those trailing new lines). Also needed to remove the LF line ending thing because Windows users.
