Ddc upgrade

[devoncarew]

@financeCoding, I'm working on gettings dartdocs.org upgraded from docgen to dartdoc. You can see the new output of dartdoc here: https://dartdoc.firebaseapp.com/.

This PR:

• moves from unittest to test
• ignores new pub files
• removes some analysis warnings
• upgrades other packages to the latest
• get the tests running
• convert the call from docgen to dartdoc; remove the dartdoc viewer step

I'm not familiar enough with this project to know how to test or run it very well. Is there a way I can test the generation path w/ having access to any of the google storage buckets?

lgtm. I think after these changes the daemon would need to be redeployed, I don't see any reason why it might fail except for possibly datastore issues. I could possibly test tomorrow night. If your feeling adventurous try restarting the daemon before merging this with (might need to make sure your gcloud/gcutil auth is defaulted to the project)

cd dart-carte-du-jour/scripts/daemon_launch
source daemon-isolate-functions.sh
carte_restart_daemon_isolate

If that works and it seems to be generating packages, then go forward and merge this, pull master to local git repo and restart the daemon again.
