CT800 V1.30 released

[Ras]

Hi,

this is the V1.30 release of the CT800. Some bugfixes, the most critical a buffer overflow with "debug on" and long input lines, so updating from V1.20 is advised. There is now a slider to control the engine strength via UCI_Elo, the throttling via node rate works better, and the engine is much stronger at super-fast time controls like 1 second per game without increments. Some minor improvements to eval and search are also in place.

This release accomodates to quirks in Arena and Droidfish with regard to threefold repetition: Arena misses the threefold when the first occurence was after a two step pawn move without e.p. possibility, and Droidfish sends the third occurence to the engine before declaring draw. In both cases, V1.20 answered with a null move that confused the GUIs, which I have removed.

Since this is a well-rounded release, I expect +3.14 Elo at CCRL.
