Android UCI engine update: Stockfish 7 beta 2 JA

Today's weather report was: Cloudy with fish rains... It seems we'll have to see some more alphas, betas and gammas before the final release.

The second beta version is compiled by Jim Ablett and this is the most recent version you can run on your Android device.

Surprise... Possible reasons are:
1) Peter's compiler is more efficient
2) 1 min is too short
3) With one core, the performance is different than with four cores
Good news is that probably nobody has time to discover which reason is the root cause :-)

Aleksei, if you have time, repeat with 4 cores, 180+2 time control and 100 games.
