Returning null from createDialog() isn't allowed, so return this as a
fallback as before. But the old code immediately dismissed it and
created another in an infinite loop. So just suck it up and display it.
And as always hope users don't see it.
Fix -- I think -- problem where game-deleted message received but not
handled by ChatDelegate would loop forever. Fix is to let non-visible
fragments take a shot, the BoardDelegate in this case. Seems to work,
but wasn't 100% reproducible AND the fix may break something else.
For some reason, in Spanish but not Catalan, filtering doesn't work with
two-letter tiles. The reason is that e.g. with RR two patterns, R.R and
RR (i.e. two R tiles, or one RR tile), are returned. The first shouldn't
be there since there are no words with RR that are spelled with two R
tiles. Until I can fix this picking the second (last) pattern seems to
work better.
If I can't figure out how to register for .xwd files, next best idea is
to encode a download in a custom url. This is one way of doing that, and
works with the urls just added to BYOD. Will likely change.
Known Players is a feature I'm devloping and right now want to keep it
capitalized as players learn what it is. It's only in debug builds at
the moment anyway.
Catch the onCancelled event, and treat as "close" button tap. Also
disable cancel via taps outside the alert, which I think is less
confusing than leaving the unplayable game up without the alert or
closing it without explanation.
BoardDelegate can have a one-to-one relationship to this thing, and
occasional leakage was preventing opening a new alert, so some fix was
needed. This one's simple.
Because I'm doing a singleton thing, if I miss the alert going away I
won't up another up. This tries to always catch dismissal. Might still
be screwed if it's not actually put up for some reason. Needs testing.
