FindDirectX Improvements
Move all the DirectX-specific stuff into a folder.

This actually allows us to compile plPipeline on *nix (although linking
will fail).
Fix clang warnings in plCubicRenderTargetModifier.
plViewTransform is not in plPipeline.

Thanks @Deledrius.
Async pyVaultPlayerInfoList::AddPlayer

This fixes the stutter when adding a buddy to the KI. The return value was
never used, according to grep. There is a delay between hitting enter and the player being added, but that's acceptable.
Minor fixes.
Clean up source groups for plDXPipeline.
Actually use working backslashes.
