Intent to de-support: traditional add-ons

To clarify, Thunderbird 72 is only a beta. We only release final 
versions on the ESR cycle, so for end users next versions after 
Thunderbird 68 will be (likely) Thunderbird 78.

So add-on authors have time to adapt until next summer, but always best 
to start early.
