Title: Add stripIframe method

In doing some work with feeds I noticed that we have stripImage available, but we don't have a way to strip iFrames which pose similar or more serious issues than images. A separate method makes sense because sometimes it is very reasonable to take the images from a feed but not to want the risks associated with iFrames.
