Add account status to myaccount page

[EPuncker]

Just a small suggestion/addition to the myaccount page, for displaying info related to premium account:

• also send an email to the user when he have 7 days left telling him that his premium is about to expire

Dear Tibia player,

This is a reminder that your Tibia Premium Time is going to expire in one week.

To extend it, simply log into your account at
    https://www.tibia.com/account/?subtopic=accountmanagement
and click on "Get Premium".

If you prefer not to add further Premium Time, your account will become a free
account once the remaining Premium Time has expired. Of course, you are welcome
to keep on playing with a free account for as long as you like. However, please
keep in mind that all Premium features will be suspended until new Premium Time
is bought.

Kind regards,
Your CipSoft Team
