Test refactoring

* Added dice bootstrap as a dependency for the bootstrap tests (wasn't
building otherwise, because it didn't always copy over the dice
bootstrap dlls)
* Updated the nuget packages to be one per dll
* Added new build configuration that modifies how stress tests run
* Updated dice bootstrap
* Added commented-code for integration tests, for when we have to debug
why ninject isn't working in tests
* Modified interest calculator to not look at charges, just if an item
is charged
