Xbox support deprecated as we no longer have DirectX 8 now.

I kept the few places in code where the define is checked as those basically didn't matter.

 --------------------------
 Changes in 1.9 (not yet released)
 
+- XBox support removed as it would need DX8 (this was about the original XBox).
 - Support for Direct3D 8 removed after svn revision 5052 due to lack of maintenance.
 - _IRR_IMPLEMENT_MANAGED_MARSHALLING_BUGFIX removed. This was a bugfix for VS2003 (in combination with .NET) which we haven't supported in a while.
 - VS 2005 support removed after svn revision 5048.
