The containers no longer force the user to use the ptrdiff_t type for
size information. For convenience, size() now always returns an int,
and the size_s() method offers a way to handle arrays with more than
2 billion elements. Internally, we still use ptrdiff_t, though.

Since so much code had to be changed, I took the opportunity to get
rid of capitalised accessors for classes that are lowercase.

MeshViewer first pass

SDL2: Mouse is back ! With correct focus support
SDL2: Added typing support with keyboard
ShaderBuilder: Refactored and simplified Shader block creation
Several warning removal
Fixed Image::Copy

and 2) fuck the Visual Studio compiler that crashes when confused.

Constants : Added minus one.

- fixed 1270 CR characters
 - fixed 56 trailing spaces
 - fixed 5085 tabs

Added BulletCharacterController.cpp & BulletCharacterController.h stubs.

Useage :
- Link action to key :
Input::LinkActionToKey(ACTION_TYPE Action, struct Key Button);
Input::UnlinkAction(ACTION_TYPE Action);
- Query action directly :
Input::GetStatus(ACTION_TYPE Action);
Input::WasPressed(ACTION_TYPE Action);
Input::WasReleased(ACTION_TYPE Action);

Also works with raw button, but not advised :
Input::GetStatus(Key Button);
Input::WasPressed(Key Button);
Input::WasReleased(Key Button);

Added RayCastResult & a naïve integration for EasyCharacterController.
Enjoy !

Added Escape button in to quit Orbital.
Added Camera control with some little damping sweetness in Camera logic in main Tick.
