Remnants of removed SCP-066 achievement in dev branch

[ChronoQuote]

When accc960 removed the new SCP-066 achievement from the dev branch, a couple pieces of it remained, including the achievement icon (GFX\menu\achievements\Achv066.jpg), and the code that triggers the achievement:

scpcb/NPCs.bb

Lines 3920 to 3923 in 6933225

	If dist < 1.0+n\LastDist Then
	GiveAchievement(Achv066)
	n\State = Rand(2,3)
	EndIf

Since Achv066 no longer exists, it'll have a default value of 0, which is the ID of the SCP-008 achievement. So currently, in the dev branch, approaching 066 will trigger 008's achievement.

This isn't a huge deal since you should already have 008's achievement by the time you can even meet 066, but it's an easy fix. Alternatively, one of either #200 or #258 could be merged.
