Added constants for GetBinaryType.

[tim-weis]

Resolves #930.

This is a backwards compatible change. All identifiers and associated values have been copy-pasted from the respective Windows SDK header file.

[nico-abram]

Relevant header code:

// GetBinaryType return values.

#define SCS_32BIT_BINARY    0
#define SCS_DOS_BINARY      1
#define SCS_WOW_BINARY      2
#define SCS_PIF_BINARY      3
#define SCS_POSIX_BINARY    4
#define SCS_OS216_BINARY    5
#define SCS_64BIT_BINARY    6

LGTM!
