Blind effect

[noudess]

I noticed that spells like flash of light and eye of confusion's Blindness effect was basically doing nothing.

From my memories of EQ, I recall that using these spells would get the mob to wander aimlessly as long as noone was in combat range. I played with the code for awhile and used some of the fear code, but tweaked target and when it was used. This seems to work ok. I was worried about making these blind spells too powerful, but since the mob attacks again if you get in range, its far less useful than fear. The mobs will also switch to anyone in range after you blind it and move out of range.

Let me know what you think. My code is deverged from the base for over a year, but I think these spots are very close still.
