Allow people to change their mind and accept the terms of service after they initially declined it

[schiessle]

At the moment a user who declined the terms of services is locked out of the system until the admin reset the ToS status in the admin settings. This means that people can easily lock themself out with no way to recover.

Idea: Once declined we should log it in the database so that the admin can see who declined the ToS. But we should still offer the user at the next login to change their mind and accept it. Simply just show the ToS again for people who declined it, same as for new people before they took a decision.

Since the other functionaity is already there we should may make the decline button action configurable instead of removing an existing (may wanted) option. Like we do it with FilesAntivirs for example.

sounds reasonable
