Added the keymap instructions for people who need to import code directly from file (i.e. GC100 users). This is useful for any case where you want to import whole custom remotes from file or even if you want to export an existing one and override certain buttons (export button info and import back into app after changes). Also good for copying devices between our software on different Android, Iphone, Itouch, Ipad devices without having to individually configure them.
