[ui] Add captcha during user signup

[marcopeereboom]

I hate capthca as much as the next guy but we need to prevent robots and floods.

An idea was thrown out there to require a user to pay a nominal fee to sign up. I kind of like that idea as well.

Thoughts?

I prefer the payment idea myself since that's something we already know we're going to need for proposal submission.

Captcha's need to be enforced by a serverside component to be any good.

#152 will eventually be the captcha.
