Committing some cleanups by avindra:

- fix numerous warnings
- make some variables unsigned
- remove redundant code and header inclusions
- make code more compact in lots of cases

Committing some additional changes by myself:
- additional header cleanups
- cleanup DX11 initialization/shutdown process (hinted at by avindra)
- Remove the cgD3D9 stuff from Externals since it's no longer needed
