Subject: [PATCH] Fix monsters not fighting back when attacked by a a parasite.

This is another corner case. Parasites have a bbox height of 24,
walkmonster_start_go() hardcodes a viewheight of 25. Therefor most
traces in other functions like visible() overshoot the parasite.
Fix this by not overriding the monster viewheight.

Analyzed and fix suggested by @BjossiAlfreds. Closes issue
yquake2/yquake2#440.
