Now stores user data in ~/.i_like_pandora.config

Removed the option to edit the youtube-dl options because ConfigParser also uses the same syntax youtube-dl uses for it's output template option. The option is still easily edited in i_like_pandora.py in the default_options dictionary located at the top.

Added a .i_like_pandora.config file to be easily moved into ~/ after changing the username, download_folder, and anything else desired. The file will work with everything missing except the username and download_folder.

Updated README.
