vcmi/server/CGameHandler.cpp
Michał W. Urbańczyk 1afcaf2817 * CThreadHelper.cpp now belongs to VCMI_lib project 
* fixed console on Windows (restored old code)
 * GeniusAI won't get blocked when it has a hero with tactics in battle
 * fixed an issue with switching turns in hot-seat mode when there is Cover of Darkness active
 * suppressed bonus system console output: it goes only to the logfile
 * [win32] setting thread names (debug purposes)
 * minor fixes
