updated Animation class and added Timers()
Changes:

- Animations almost done
- Added abstract class: BaseObject.
- Internal game Timer counter is updating now

What's left:
- Updating surface's rect, so Draw will render only one frame of animation
- Few tests to check if everything works and nothing crashes :)
Animations completed

not tested
