Fix some weird stuff

I fixed a bunch of really weird things in the tweak's source code. It's strange to return %orig() in a void function rather than just calling %orig(). Also, I have no idea why you would assign arguments different values and then just call %orig() anyways rather than using %orig() with arguments. And there were some methods which assigned their arguments different values, but then simply returned, so I left the returns and removed the other stuff.
