Subweapon

This value is used to "remember" if the player has the Shrinker or Expander selected when changing weapon.

Works like a bitfield, with the only value used in Duke Nukem 3D v1.5 being 2048 (one shifted left by GROW_WEAPON) if the Expander has been used instead of the Shrinker last time, otherwise it equals zero.

Identical to bsubweapon, except it interprets the value as true/false for each weapon.
