7c75c83859 Set engine strength using Elo value 
Remove the Strength preferences setting.

Add a new left drawer menu item to set the current engine strength in
terms of Elo. Supported for all engines that implement the standard
UCI options UCI_LimitStrength and UCI_Elo.

Elo settings are remembered individually for each engine.

00c59c0247 Add UCI_Elo support to CuckooChess 
If both "Strength" and "UCI_Elo" is used, "UCI_Elo" tases precedence.

Internally UCI_Elo is converted to a Strength value using a lookup
table that was calculated by playing games against Stockfish 11 using
its UCI_Elo implementation. The time control was 60+0.6 on computers
where Stockfish bench reported about 1.73e6 NPS.

67e03495dc Implement maxNPS UCI option for CuckooChess 
This is an alternative way to limit the engine strength. It also has
the advantage of reducing heat and battery drain.
