Preserve account feature

This feature only works for those who linked email to account, and using it without doing so will prompt you to link your email.

This makes the feature largely redundant, since linking an email prevents your account from being deleted for inactivity as long as you have at least 1 hour of playtime.

@InterAction_studios

Deleted users who haven’t logged in during the past week and have less than 10 minutes of playtime, and also users who haven’t logged in during the past 4 weeks and have less than an hour of playtime, and also users who haven’t logged in during the last 12 months and haven’t set an e-mail. Note that users with any purchase are never deleted.
