Change Simple Text Append/Prepend Title Name/Order

There are two methods for appending and prepending text, one which is simple, and one which is advanced. The simple one is called Simple Text Prepend/Append, and the Advanced one is called Regex, because I assume that's what's used to prepend or append the text.

I think that usability wise, people know that Regex (a techno-sounding name) is more advanced, and the simpler name title is what they should go with. Also, since they are under a Simple category, I assume people would assume as much.

I'm not sure if this is a step forwards or backwards, but I also wanted to create a patch for the first time ;)

This is a placeholder, a patch should be up in a bit. Cross your fingers ;)
