Add setting to skip migrations when building test db

We periodically add data via data migrations. However with test-utils,
the first time you run tests that depend on that new data, they work but
subsequent tests will fail.

However, this is the same situation we had with schematic. We use model
makers to generate data we need for tests.

Ergo, there's no reason to run the south migrations to create the test
db.

This shuts that off.

Fix generatedata

* the hacking howto has instructions for creating the db that don't
  include setting the CHARSET so it would die on creating revisions
  using the revision model maker which includes unicode data
* the revision model maker code value strings were ... "interesting"
* cosmetic: i tweaked the formatting in the MozillaNews.wiki
