Android UCI engine update: Cheese 1.9

Patrice Duhamel updated Cheese to v1.9. Its previous version is rated 2602 ELO in last Rapidroid ranking. I hope 1.9 will add at least what the author measured on Windows:

CPU: i5-2500 K
Versions: 64 bit
TC: 10" + 100 ms
Hash: 128 MB
Openings: Adam-Hair-8moves-100133.pgn

Rnk Name       Elo + - games sco drw
1   Cheese 1.9  26 4 3 10000 58% 41%
2   Cheese 1.8 -26 3 4 10000 42% 41%

Remember that the Xboard protocol is recognized too by Cheese although it's not mentioned in the filenames. I never tested Cheese with Xboard yet, since UCI works pretty well.

This time there's a 64-bit build included too. Bon appetit!

Version 1.9 - May 6th 2017
* fix possible crash : not initialized variable for castling
* fix rare crash in very long games
* reduce pawn hashtable structure size
* change main hash table structure
* remove early queen move penality
* remove lost castling penality
* more reduction in LMR based on move count and depth
* null moves pruning reduction based on depth
* use config.ini for default values in UCI mode
* add logfile option
* rewrite move ordering and generation
* reorganize search code
* release armv8 version
