GOB: Add constants for different surfaces/sprites

Add
static const int kFrontSurface   = 20;
static const int kBackSurface    = 21;
static const int kAnimSurface    = 22;
static const int kCursorSurface  = 23;
static const int kCaptureSurface = 30;
to class Draw and substitute the raw numbers in other files with
those aliases, for readability.
