Hide possible culprits on "claimed" builds
Acceptance tests should run correctly on sauce labs

Closes #41 and #51
Merge pull request #49 from drekbour/claimed-build

The decision of whether or not indicate culprits on claimed builds is now moved to the back-end. This was this behaviour could be made configurable.

Addresses #40 and #49
