[live mode] Wait a certain amount of time before adding the role

As per RstY_CZ#2033 here

This is harder than I first thought:

1. User starts playing
2. In the timeouts table, a blocker for that user for the selected time is created
3. User activity gets ignored while the blocker is active
4. When the blocker times out and the user still has the activity, the user gets the role
5. When the status doesn't the activity, an allower is created with a timeout
6. When user starts playing again, allowed is cleared and role is given.
7. User stops playing, allowed is created
8. Allower times out, start at 1. again
