[FE6/7/8] Blank bonus in terrain info window

Some terrain (such as thicket and fence) have blank def/avoid values in the terrain info window. This is linked to berserker-type movement (FE6: 60C714, FE7: BE398C, FE8: 80B90C). If berserker movement cost for terrain is <= 0 then the terrain info window will be blank.

If you don’t want terrain bonus display to be linked to the berserker movement type, then change the pointer at the below addresses to a list of 00/01 bytes in free space.
