Update ConnectionManager to use new Connection class.

Update ConnectionManager temporarily to work with the incomplete
database layer. Fixtures are not functional at this time, but at least
getDataSource() works.
Update home pages.

Code changes are required now that 3.0-database has been merged.
Update ExtractTask tests as line numbers have changed.
Add test incomplete markers for tests relying on fixtures.

Fixtures are totally hosed right now, so mark all those tests as
incomplete until the new fixtures/schema system is completed.
Fix config file name location.
