Shared/Util: Introduce a task scheduler which schedules task with c++11 techniques.

* Use std::function as callback (methods, lamdas & std::bind).
* Uses std::chrono::duration as duration type (Milliseconds, Seconds...)
  - With c++11 user defined literals we could just write "11s" for example (MSVS 2015, gcc & clang).
* Provides a lot of overloads for easier usage:
  - Static durations or random durations between min and max.
  - Named (with group ids - group id 0 is possible) or anonymous tasks.
  - Asynchronous tasks.
* Is adapted to the current needs of scripting:
  - Repeat tasks through the TaskContext
  - Schedule new tasks from the context.
  - Provides access to the times repeat counter of a task,
    this will help to schedule multi step events (dialogs for example).
