Bug with weaponspeed patch

[Moonchilde <jtraub+@cmu.edu>]

Here is the patch for truncating weapon speed at zero.
Before, a dagger + 4 would try to give a player a weaponspeed of -1
but since weaponspeed was an unsigned char, it wrapped and gave them a speed
of 255.  I don't see any real reason for weapon speeds FASTER than bare hands,
so, here is the patch.
