* Reverted std::bind to boost::bind. std::bind on Visual 2012 doesn't work in some cases (especially with std::ref), not sure why [but it seems to be a bug, since 2013 preview compiles the same code fine].
* Move assignment operator for VS 2012.
- use std versions of function, bind and ref
- OVERRIDE -> override
- NULL -> nullptr
- use std versions of random distributions
NOTE: this may be last revision that supports gcc-4.5
* disabled features unsupported by MinGW
* fixed issues with DLL_LINKAGE
! BOOST_THREAD_VERSION in now 3 workaround for existing code added, consider refactoring.
* some small tweaks ("-fpedantic" warnings)
* all lock/unlock and unlock/lock pairs are done by RAII guards now
* fixed two possible crashes at the end of battle when last stack was killed by spell. That should fix#749 and #752.
* fixed a very nasty race condition, eliminating possible deadlock at the start of battle when human hero has tactics
* fixed#422
