Players paying a blind can be moved when splitting tables

[ctm]

Fix it so that some players are ineligible to be moved when splitting tables, even when folded.

Oh, as a side note when splitting tables, I noticed mb2 sometimes takes the BB if they've folded and moved them to a new table. Most sites I play on make sure to keep the blinds at the table they're at and only move those UTG to button, most real life tourneys work this way too.

There is separate code for a one player move for rebalancing and the code for table splitting. I should examine both.

My recollection is that for rebalancing we do it at the end of hand and won't take a blind. Additionally, nobody has pointed out a problem with the rebalance motion, but I should still double-check it.

For table splitting, it's just a matter of adding constraints to Table::movable (which perhaps should be renamed movables, since it is not a predicate and returns a Vec<SeatIndex>. AFAIK, all we have to do is exclude any SeatIndex that occurs in either blind_seats or solo_ante.
