I updated the site dependencies, and it broke logins again.

Anyways, this lead me to finally vendoring the password encryption wrapper library the site uses. Hopefully this should fix the problems in the future.

Additionally, signup now requires filling out a simple captcha. I've been having issues with people effectively using the site to spam a e-mail address. This should hopefully at least make it a little bit more involved. I've deliberately chosen a simple, self hosted captcha implementation because I don't want to feed the creepy google data-mining project that is ReCAPTCHA.
