Changeset 6255 for metadata/trunk/toolkit/src/test

Now follow the default Maven layout, so we can easily leverage standard testing facilities.

First test based on Adelheid 1.1 profile and record tests:

• upgrade of a profile conforms to 1.2 cmd-component.xsd
• upgrade of a record conforms to the 1.2 profile XSD

Additional records collected at the CLARIN Centre Meeting May 2015 are also added, but still need to be worked into tests.
