MDL0 DrawXLU bugfix
MDL0 null strings bugfix
Don't need this; I'm going to use GL.Viewport to render multiple viewports within the same control
Add DEBUG to debug build's title and set updater to use version number from the assembly title so we don't need to write it twice (so lazy)
Link model panel events to checkboxes
Make ARGBPixel and Vector4 serializable, removed unused bool from MDL0TextureNode, remove XLUMaterial filter from material drop down list, don't set model panel checkboxes when updating
Rewrote viewer settings to use .NET binary serialization, moved bone rendering back into model render code so IBoneNode isn't an IRenderedObject, minor fixes
