Most of the ReaderMode.jsm and Readability.js code is only needed when we actually need to render a document in reader mode, but also winds up loaded into any process where we ever check if a page is readerable. This winds up wasting a huge amount of memory (and probably a huge amount of CPU time) loading code which is almost never used. This patch splits ReaderMode.jsm into two modules, one for checking readability, one for actually entering reader mode. It also separates out the isProbablyReaderable checks from Readability.js, since the overhead of loading that script before it's needed is unsupportable. This means we're probably going to need some effort to keep Readerable.jsm and Readability.js in sync, but the code in question is pretty trivial, so it shouldn't be too difficult.
