Subject: [FD] Hilariously Bad SQRL Implementation

If any of you are familiar with Stephen Gibson's SQRL protocol for user
authentication (really neat idea), you might have come across this PHP
implementation before:

Unfortunately, this library is actually pretty terrible. Not only does it
pass all of the data off to a Heroku app to perform the signature
verification, it is also vulnerable to SQL Injection:

I thought about submitting a pull request to fix this, but I don't believe
there is honestly much here to salvage. So, I'm writing my own
implementation here: <- Not ready, at all, for even beta

P.S. Also, it uses mt_rand() for challenge generation in a crypto library.
Tsk tsk.
