Crash due to typo introduced by Weblate made me realize I wasn't running
the script that ensures translated strings have the same set of format
specifiers as the English -- which might not be strictly necessary, but
it's safer to enforce it for now. Moved a few remaining %s to %1$s style
while at it.
Lots of work dealing with banned permissions (SEND_SMS and
RECEIVE_SMS). First, if they're banned and NBSProxy is installed, just
use it as if the permissions had been granted. When it's not there,
explain at various points where users will otherwise be confused: when
they try to invite using data sms, or when they open a game that already
uses it.)
When those became an advanced feature I added a warning for upgrading
players who'd miss them. That was long ago, and the warning was only
supposed to last a release or two.
