Added #1090

If a user clicks the user activation link, the user will be automatically logged in without a message saying anything. Do you think there should be a message indicating that the account is active and that they are being logged in ?

The following check takes place before logging the user in: The user must match 32 and 16 character alphanumeric  strings (user_lostpass and user_token) that they receive in the activation email, must be in main group "4" ( they meet this requirement when they match user_lostpass and user_token since their account is technically activated but not logged into yet), and can't have a registration date older than 2 days. If the user fails everything but the lostpass, then they can still activate like normal but must log in manually. This allows this to be backwards compatible if a user had received an e-mail with an activation link before this change and/or if the activation is older than 2 days.

If this gets accepted, other language files must be updated.
