[Toolkit.Game] Added generic method overloads for IServiceRegistry and its implementation GameServiceRegistry (issue #175).
[SharpDX] Removed 'Empty' static fields from Point structure as it is semantically incorrect.

Update README.markdown
Adding proxy functionality in constant buffers (in effects framework) for sharing buffer from multiple effects
Adding Update method for constant buffers ( update a constant buffer without applying a pass )
add function to decompose uniform scaled matrices
Adding Matrix3x3 class

This matrix is used to store scale and rotation only.
This is only 9 floats instead of 16 , almost half the 4x4 matrix, which makes it much smaller and faster since it has to do half the operations (and in cases like determinant and inversion even less than half)
