Rewrote + Refactor + Implementation

REWROTED InputManager, SOME REFACTOR, IMPLEMENTED SIMPLE QuestManager

InputManager now not event-style. It's just check keys on Update(...)
and
work with pressedButtons Hash. I think that with custom associations
and group of buttons it will be fine and ended. [Working on]
QuestManager now is not clean and is very simple. Working on simple
event
system that presents by EventMager. Now can carry list of quest with
one active at once. Do not work with EventSystem by itself. [Working on]
Some refactor at many places. Try to keep code simple and clean.

Roadmap:
+ Make InputManager ended: implement group and better management with
groups.
+ At this moment EventManager is bad. Tried to use .NET EventManager,
but
it's don't provided on Compact.NET so it's won't work on XBox.
+ Also I have to make WorldManager and StatementManger to clean code and
in order to provide game more big with less pains.
+ It's seems good to implement custom ContentManager Pipeline, but can't
do
it now becouse don't know how =/ Many tutorials in internet provide
information
and sample project, but if I made it myself something going wrong.
