Android UCI engine update: Aristides 1.0.20170619.ACH

THIS is a new build of Aristides for arm7 by Alexei, using PGO optimizations, typically faster by 5% to 10% approx than a standard compile. There's already a more recent build available, so take it for collecting purposes only.

Aristides is a C port of the Stockfish chess engine, forked from Cfish by Michael Byrne. It includes play by UCI_LimitStrength (play by ELO rating), UCI Move Delay, Fast Play when mate is found, Study option (from Matefinder), Hide Info ( some information output may be skipped to reduce output) and various search tweaks.
