Added Settingsfile & Minor Code cleanup
A settings.txt file is created and filled with the hard-coded values if none is found. If one is found its content will overwrite the hard-coded values. Checks if the internal version string matches the settings.txt file before loading the values. The settings file ignores lines not matching the regex: ".*=.*"dev
