Make signup process less ugly/jarring now that we have Recaptcha

[dsjoerg]

Our email provider cut us off because some bots were abusing the site to send password phishing scam spam to random email addresses.

I implemented Google Recaptcha today, got it working, but it looks ugly and jarring to the user because they have to enter their username/password twice, and on the second screen the styling is all off. So the issue here is to make them do it only once and keep the styling nice & consistent.
