Publish 2.04 to pypi

[CrashenX]

https://pypi.org/project/ofxclient/ has 2.03 which is broken with Discover.

I was able to get Discover to work by updating my requirements.txt to:

-e git+http://github.com/captin411/ofxclient#egg=ofxclient

And changing the Discover URL to:

https://ofx.discovercard.com:443

I encountered the "TypeError: option values must be strings" issue with version 2.0.3 (see #31, #51) and managed to install 2.0.4 from source with:

pip install git+https://github.com/captin411/ofxclient.git --upgrade

Please publish 2.0.4 to PyPI so this is easier for other users in the future.
