Updates and additions to APIs in Thunderbird 77

Thunderbird 77 beta 1 is here. There's not many changes for 
WebExtensions in this version, but there is a significant one.

  * Several improvements to tab handling and events.
  * Content scripts in the compose window. This allows you to interact
    directly with the message being composed, and should solve a range
    of problems.

Here are the details:

Looking ahead, with Thunderbird 78 being the next release, I won't be 
working on any new additions for a while (other than the compose 
attachments API, which is already finished). Instead, any time I have 
for WebExtensions work will be spent making sure existing things work as 
they should – like the changes to tab events mentioned above. I already 
have a long list of bugs, so I'll be focussing on the ones that make the 
most difference to the most people. Sorry if your pet problem doesn't 
get fixed.

Lastly, thank you to those who have tested new additions and pointed out 
problems or things that have been missed. Thank you especially to those 
people who have contributed fixes to the issues they see. You know who 
you are.
