We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Whether or not tiles moved used to be determined by comparing new_tiles
with m_tiles. This is no longer possible since the slide is done
in-place.
This fix makes the game look through the m_sliding_tiles, which contains
previous and current position for each tile on the board, to determine
whether any tile moved at all. If not, the move is deemed unsuccessful.
Fixes#8008.
Maximizing the board population still takes priority, but if there are
tile generator "moves" that result in equivalent board population after
a player move, the one with the lowest score is selected.
