Code isn't compatible with example dbs from MS at codeplex

[FransBouma]

The example Adventureworks DBs from Microsoft at codeplex (https://msftdbprodsamples.codeplex.com/releases/view/93587) are not compatible with the code as the all lack a table (Contact) and have slightly different types in some other tables. To make more people able to work with the code, the benchmark should be converted to the schema available on the codeplex site, e.g. the 2008 schema (which is equal to the 2012 one)

The code in source control at codeplex does have the right schema / data, but it's not easy to import it (csv files).
