Random club frame

This is initialized to zero. The comment in the code says 'Glowing'.... For WW2GI, this is incremented by 64 each frame if the current has the WEAPON_FLAG_GLOWS flag. Also, if it's not zero, you can't fire the shotgun (I don't know why...) When the shrinker or grower are dispalyed on the screen, tile SHRINKER +2 is drawn using this as a modifier, then the normal weapon is drawn.
