Use superagent from npm.

Needs testing

Closes #58

[XhmikosR]

I'm pretty sure superagent.js is a browserified build of an old superagent version. It's only used once in

slackin-extended/assets/client.js

Lines 45 to 65 in a08fb6c

	function invite(chan, coc, email, gcaptcha_response_value, fn) {
	request
	.post(data.path + 'invite')
	.send({
	'g-recaptcha-response': gcaptcha_response_value,
	coc: coc,
	channel: chan,
	email: email
	})
	.end(function (res) {
	if (res.body.redirectUrl) {
	window.setTimeout(function () {
	topLevelRedirect(res.body.redirectUrl)
	}, 1500)
	}
	if (res.error) {
	return fn(new Error(res.body.msg || 'Server error'))
	}
	fn(null, res.body.msg)
	})
	}

Judging by the year I'd say the version was 2.x. So, now it will be 3.8.3. https://github.com/visionmedia/superagent/releases/tag/v3.0.0, which we should be OK.

That being said we can just use XHR later and get rid of the dependency for the frontend.

But before we proceed with merging this I'd like to revert any changes we made to the file. I'll make a PR in a few.

NVM it was easier to push it here. Just don't squash the patches :)

Also note that I haven't actually been able to test this myself.

[XhmikosR]

@emedvedev remember not to squash this

[XhmikosR]

Actually wait, it seems superagent.js isn't found on Now with this patch. Works fine locally though.

[emedvedev]

Yup :) It also doesn't currently work with Now, trying to fix.

[XhmikosR]

There is an upstream patch for Now rauchg/slackin#399. Maybe this helps you simplify the Now deployment.

[emedvedev]

Updated it to work with Now, too.
