Pending Morse Elmer 1.7.1 Release - mighty bug fixes

After I release 1.7.0, I already had a list of bug fixes I wanted to address next. But this release goes way beyond that initial set of bug fixes. I ended up adding new (requested features) Reformatted the settings and documentation to make it more accessible to those just starting out using Morse Elmer to learn Morse code. Hopefully all of these changes will help the new users to the app and not piss off the established userbase. :D I still have a few other minor changes in the pipe line, but I think I'll wait to see what the reaction (if any) to these most recent changes.
