Thanks for your work on this, mwayne. I added in moving mru.json and portablization of that and config.json as well as preservation of all moved files in the case of an upgrade after a crash. I also added in all the dictionaries available. Updated the Default config.json so the updater disable isn't reset on launch. And taskbar pinning.

Sometimes, the impossible can become possible, if you're awesome!
