New colors for missed hits

Date:Fri Jun 22 16:45:37 2012
Thanks to Oisín and Mint, we now have (as of the next reboot) different colors
for missed hit.

Use "cha col miss blue" and "cha col avoid-damage green" to set the new colors
to something.

For those with XML-mode clients, said clients may need updating to handle the
new corresponding XML tags.
