[1746014] Added an implicit quiver when firing missiles:

 - ^P/^N change the selected missile, but only within a fire_order slot.
   i.e., if you're wielding a launcher and have "launcher" first in your
   fire order, ^N and ^P will cycle only through suitable launcher ammo.
 - If you use ^P or ^N to change the default missiles offered, that choice
   gets saved as your quiver (unless you cancel targeting).
 - Fire always offers the quivered item first, if appropriate (so if
   you have darts quivered and try to shoot from a bow, the darts will
   not be offered).
Breaks save compatibility (quiver is saved).
