[NSFW] Alias /ss/ into straight shota

https://derpibooru.org/tags/fwslash-ss-fwslash (I can’t link this properly due to the “-” at the end, sorry) -> straight shota
 
Both are fairly common terms, and while the /ss/ tag isn’t all that populous it’s bound to get used by someone in the future, and should probably be merged into straight shota.

@Napsack  
“/ss/” is a self-referential meme though, like >>816789 and >>1048728. i think it would be better to just remove it from images where it isn’t referenced.

@DanielTepesKraus  
Alright, noted. Should /ss/ imply straight shota then, seeing as it’s a meme that implies the latter activity?
 
Edit: Oh, and we should probably add descriptions onto the tags if we want to use them like that.

@Napsack  
No, because saying /ss/ doesn’t mean actual shota is happening (the meme is often used to only imply it could happen), which is what “straight shota” is for. Thus, it should not imply it.
