Make Passwort-Reset possible for non verified users.

[appinteractive]

Currently it seems that a user that did nor verify its email, can't use the password reset feature. But without loggin in, she/he can't re-trigger its verification mail.

So we should ether resend the email after a certain amount of time or make the passwort-reset feature possible event if the user is not verified.

Also there might be an possible issue with not using the to lowercase on the email addresses while resetting.

issue is solved on #77 and will be merged with it.
