continuous integration testing 

This includes a mysql dump of a wikirate test database that is used for integration testing. Don't know a good way how we can maintain this data in the future.  The problem is that `wagn seed --test-data` corrupts the wikirate db and vice versa loading the wikirate dump corrupts the test data. 
these config files are in gitignore; I don't get how they're here?

several of these would definitely break things (eg database.yml)
