Redqueen v0.7

[bhlangonijr]

Hello.

1) Fixed bug at time management code. It was preventing Redqueen to play correctly using incremental TC. Reported by Ingo Bauer. Thanks!
2) Transposition table code was refactored;
3) Aspiration window code was improved;
4) Implemented Pawn on 7th rank extension;
5) Cleaning up in search code;
6) Search code was changed to use "fail-soft" framework;
7) Minor improvement on pawn & king move generator;
8) Changed piece material values;
9) Fixed bug at zobrist hashing code;
10) Fixed bug at function which verify legality of moves retrieved from hash;

Source & linux64/win32 binaries: https://sourceforge.net/projects/redqueenchess/
v0.7 svn tag: https://redqueenchess.svn.sourceforge.n ... elease-0.7

I expect a substantial Elo improvement as bugs #9 & #10 were causing big instability issues in the search.

Regards,

It's impressive for a new engine. I'm sure it will get better in the future.
