-Systems, Components and Events now must have proper mixin. Mixins are located in ecs.core module. (i.e. mixin ECS.Component)

-Multithreading support:
 *multithreaded update - updateMT(), function generates jobs to execute
 *added dispatch callback function to dispatch generated jobs (setJobDispachFunc)
 *added getID callback for get thread ID by EntityManager
-added Job structure. Job has one function "execute()".
-calling partial info update (required to multithreading)
-multithreaded removeEntity, addCompoenents, removeComponents. Every thread has own data and remove/change lists.
-multithreaded addEntity (WIP)
-fixed issue with duplicating components
-simpler and faster "findBlockWithFreeSpace" function
-CallDataAllocator, allocator for CallDatas (used for Jobs)
-fixed some bugs/issues
