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

also commands will give double sends should you choose to implement this version
to fix this go to line 487 in bot.java and delete that send message and that should stop the double sends

ill try to add more data input checks so people arent breaking the code its very very loose at the moment and should only be used for people who know what they are doing when adding links
