EML

This is the release tracking bug for the final (yeehaa!) release of eml:
eml-2.0.0. Need to finish these things before the release is cut:

1) change all namespaces to eml-2.0.0
2) regenerate all png images where needed
3) generate release docs and proofread them
4) tag sources and call for a vote on the release from project members
5) cut the release and be done with it

Anything else? Add it here and I'll see its done.
