Reflect late wordlist changes.

Due to an editing error, there were two terms missing in the en_nouns
list. Also add a regression test.

must face the problem, that it is not easy to generate proper welcoming
wordlists automatically. Any further hints/help welcome.

Additional fixes for python3.4 `tox` runs.

Badges are now generated on github.

structure. These are easier to memorize.
