Save and re-load user settings in the local (non-roaming) application data folder.
The location of this folder depends on the path the Window Shell returns.
For me (on Windows 8.1): "C:\Users\jonathan\AppData\Local"
So the full path for me is: "C:\Users\jonathan\AppData\Local\JynxEmulator\JynxEmulatorSettings.config"
Readme.htm update regarding the user settings file.
Update to the about box, as I think everyone else at Camputers deserves a mention(!), and to include the link to the github project.
