I think clean up DX11 code a bit. Used "smart" pointers to avoid need to manually AddRef/Release in many places. Eliminated the D3DBlob class (replaced with just D3D10CreateBlob). Eliminated some Init/Shutdown functions (moved stuff into ctors/dtors). This should not affect behavior at all, only code maintainability.
