made the Q key double as a trigger for the emoji overlay in the default mobile-intl layout

This makes the emoji overlay accessible without sacrificing an extra key.
There are (afaik) no languages with diacritics on the Q anyway and it's

being that the hint applies to a long press rather than a shift-press as
with most 2nd labels, but better than no hint at all.

 overlay functionality with the ``-O`` flag or by setting the environment variable ``SVKBD_ENABLEOVERLAYS=0``. There is
