Acts 332 change of namespaces to support dd4hep 1.00.01

Fixes ACTS-332

The new DD4hep version has a simplified namespace structure (and capitalization), as well as moved some functionality. The cases for which ACTS code had to change were:

to call worldTransformation on a detector element, you now have to specify if you want "nominal" (ideal) or "survey" (measured) location.

verifyObject() does not exist anymore. it used to throw an exception if the handle was assigned the wrong object type, but the exception is now thrown automatically, either at link-time or at runtime during assignment.
