New build flag required

As of a few hours ago, you'll need to add a new flag to your mozconfig, 
or Thunderbird will think it is Firefox in a number of places. This is 
the line to add:

ac_add_options --with-app-basename=Thunderbird

This change was brought to you by bug 1657954 
<> on 
mozilla-central, and bug 1658682 
<> that I followed 
it up with. I think that is all that is required – our builds and tests 
are running again – but if there are any further issues then the latter 
bug is the place to go.
