[pard] [2.0.13] Factoriopedia does not show speed stats for strafers and stompers

[ChefOfRamen]

I wanted to look up stats in Factoriopedia to see how many rocket turrets I would need to kill a stomper.

What I expected: speeds were listed like with biters, spitters, and wrigglers.
What happened: no speed was listed for any size of strafer or stomper.

I have not checked if this happens with demolishers.

Displaying values for the strafer and stomper would be very tricky. It is hard to calculate, and showing some close value in an ideal situation could be really misleading. Values for demolishers were added. This fix will be part of the next release.
