Fixed issue kevinstadler#12

Fixed issue kevinstadler#12 . I wasn't able to directly alter the values of setting through the API's .set() function, so I created a function returning a copy of the settings instead.

If someone knows how to load the default settings, that would be better than using a hardcoded dictionary with their values.
