When registration email verification is enabled, the user should be informed upfront that a confirmation email has been sent to activate the account

At the moment, if 'Use Email Verification' is enabled from Administer Wiki > Users & Rights > Registration and an user completes filling the credentials on the registration page, even after clicking 'Register' he is not made aware that an email has been sent to the provided email address in order to activate the account.

Only after clicking the 'Log-in' button on the Registration page, a Notice is displayed stating that the account is not yet active because the email has not been yet confirmed, but the thing is the user didn't know until this moment that the instance sent an email that needs to be confirmed.

Regardless of the Notice (which is good to be displayed in case an user still clicks 'Log-in' without confirming the email), the info should be displayed on the Registration page, just after the user clicks the 'Register' button.

Instead of the current: "Registration successful. You can now log into your account."

it should be something like:

"Registration successful. A confirmation email has been sent to the email address you provided. Please click on the link inside to activate and log into your account".
