..to point to 2.x documentation instead of 1.x (and to be consistent with other links on the page)

It's not stable yet, and Webpack repo points to 1.x docs. Why make the change?

[aweary]

@gaearon you linked to webpack.js.org twice in db140c8 (one, two) when you added the links, I assumed that was intentional? I can change them all to the 1.x docs if it wasn't.

ping @gaearon, did you want me to change all the links to point to 1.x docs instead?

[gaearon]

Looks like I linked inconsistently, even db140c8 includes both style of links. I'd say let's change them all to point to 1.x, wanna do it?

You bet I do!
