Introduce additional rotatesprite bit for internal use and mask ext. ones from CON.

ROTATESPRITE_MAX is moved to build.h and all orientation bits from CON commands
using rotatesprite are ANDed with (ROTATESPRITE_MAX-1).  Some of the functions
use ROTATESPRITE_MAX for different internal purposes, which will not be exposed
to CON now (a good thing).  Also, dorotspr_handle_bit2 is made clearer.
