switched over nsfw command to new format

you can now type .nsfw <optional tag> for a more specific type and when
adding nsfw you just add an extra param at the end with tags i.e
tag1,tag2,tag3 no spaces of course

also hopefully this doesnt break anything but i believe the .class files
are gonna be deleted
