Improve multi-threaded mate finding 

If any thread found a 'mate in x' stop the search. Previously only mainThread would do so. Requires the bestThread selection to be adjusted to always prefer mate scores, even if the search depth is less. 

I've tried to collect some data for this patch. On 30 cores, mate finding seems 5-30% faster on average. It is not so easy to get numbers for this, as the time to find a mate fluctuates significantly with multi-threaded runs, so it is an average over 100 searches for the same position. Furthermore, hash size and position make a difference as well.
