* Hackish solution allowing AI undertaking actions from event-handling thread
* Fixed crash when death stare or acid breath activated on stack that was just killed
* minor fixes
* Brought shared_ptr and unique_ptr and their factories (make_shared, make_unique) to the global scope.
* Removed excessive usage of shared_ptr in bonus system interface.
* Fixed bonus system limiters/caching interactions. That covers #823, #859 and a number of rare edge-cases.
* Implemented multiple-step limiters applying, fixing hasAnotherBonusLimiter and allowing transitional dependencies between bonuses.
* Bonus system should be slightly faster, since we cache limited bonuses. Some rare usages (limiting query against a foreign node) however can't use caching.
* 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
* fixed crash when creature is casting Hypnosis (ie. exped Vampire Lords)
* fixed crash when creature is casting Cure before attack (ie. exped Unicorns)
* fixed crash when creature is summoning elemental (TODO fix it)
* fixed crash when doing a bonus system operation with a hero liberated from prison (ie. entering town or battle)
* fixed deadlock when StupidAI tried to assault the turrets
* fixed never ending siege when StupidAI has to use catapult (no more deadlocks on AI-AI siege)
* fixed deadlock when a hero received a level during another player's turn (ie. when he successfully defended)
* AI can win the game by defeating all enemies if there is a specific victory condition applying only to human players
* added options to help testing adventure map AI (--onlyAI, --autoSkip and --oneGoodAI).
* many minor changes
* Fixed#736, #737.
* Fixed crash on loss/victory.
* Fixed crash on loading some AB maps.
* Fixed crash on loading map where victory/loss condition objective hero was placed inside the town.
* Fixed crash on loading map when neutral Dungeon has built Portal of Summoning.
* Mutex protecting GS will be used to prevent changes in GS when GUI might read it.
* Little more securities around moving hero and ending turn, still needed more.
