I did some refactoring on the electrum (and native) endpoints, splitting them into their own files, grouped by category, as they were getting big. Got some details on the electrum interface from the network dev. Some minor tweaks required based on undocumented history. Comments added to our code for that. We'll have full support for electrum v1.0 - v1.6 (current).
