Add 'This wasn't me' to reset password E-Mail

[obendev]

Hey, I thought of an option where you can click a link "This wasn't me" in the E-Mail which you get if someone tries to reset your password.
The IP of the attacker could be saved in the bruteforce table and be banned for the amount of time set globally in bruteforce settings.

If you can name me the files where I can see how an IP gets banned, I can also code this function myself.
Although im probably not able to code the E-Mail link.
