Fixes IndexError on save with removed member forwarding email (#11)

* Fixed IndexError if a non existent field gets queried for a value. Using dict.get to either get a value or provide a reasonable default
* Removed list construction around new_key value
* Clean up source code with 80x25 terminal and vim (complies with PEP-8)
* Added some docstrings
