Bugfix: DirectX effect files used sampler states in wrong order.

Sampler info stores textureSlot and samplerSlot separately.
SamplerStateInfo._dirty is true per default to always create a sampler state.
Rebuilt stock effects.
Incremented MGFX version.
Bugfix: SamplerStateInfo._dirty must always be set when a property is changed.

Fix window sizing craziness on Windows. Now to check Linux.
Change location of clearing updateClientBounds to make sure OnResize is executed when client rectangle is changed.
Mouse Cursor not hidden in XAML based apps.

In xaml, mouse must be actively turn off during initialization.
Seting Game.IsMouseVisible =false; has no effect because the code check
against current value, which is by default false;
Now, In order to hide the mouse cursor one must do
IsMouseVisible = true;
IsMouseVisible = false;

Another thing: The execution path through
MetroGamePlatform.RunLoop()
MetroGameWindow.RunLoop()
which call SetCursor(false), doesn't seem to be active anymore.
uncomment code
OpenTK, Linux and resizing windows
OpenTK on Linux currently does not allow the window to be resized if the border is fixed. We get the resize event for the intended size, then immediately get a resize event for the original size. This was preventing GraphicsDeviceManager.PreferredBackBufferWidth and PreferredBackBufferHeight from having any effect.
