WineD3D: BltFast/BltOverride color keying

[Roderick Colenbrander]

Use this version instead as the previous one didn't compile due to an extra '(' :(

> Hi,
> 
> This patch adds color keying support to *_BltOverride. It required changes
> to *_BltFast to properly pass 'BLT' flags instead of 'BLTFAST' to
> *_BltOverride. Next it adds SRC/DEST color keying to *_BltOverride.
> 
> Further to get color keying working at all it fixed a small error in
> LoadTexture which I paste here because it is hard to spot in the patch. Right
> now a check in there looks like:
> (This->Flags & SFLAG_GLCKEY && !(This->CKeyFlags & DDSD_CKSRCBLT)) ||
> /* Reload: vice versa  OR */
> (!(This->Flags & SFLAG_GLCKEY) && !This->CKeyFlags & DDSD_CKSRCBLT) ||
> 
> The third '!' was removed as indicated by the comment this fixes color
> keying. Next to this some gcc warning was silenced by adding some more braces.
