[1.7.4] Bikini available without unlock, but unlock still exists

[ScienceBall]

From what I can tell, the cosmetic option to wear a bikini/mankini does not check any unlock, and therefore it can be used from the start of a new account. (I heard that previously it did check.) But the unlock "cosmetic_bikini" still exists, and this unlock is still obtained by talking to Melinda at the Sher'Tul Fortress, and this unlock still has a message that displays when you unlock it.

I don't know which side of this is a bug - whether it was a deliberate change to make the bikini option available from the start (in which case the game shouldn't say you've unlocked it), or whether the bikini option is meant to still require the unlock.
