Remove ServiceLocatorAdapter.dll

The only class ServiceLocatorAdapter.dll implemented was
StructureMapServiceLocator, which had only two simple methods.
Since nobody remembered where ServiceLocatorAdapter.dll
originally came from (which makes it hard to maintain), I
implemented the functionality of those two methods in our own
code and deleted ServiceLocatorAdapter.dll. Also renamed
the former StructureMapServiceLocatorWrapper class to
StructureMapServiceLocator.
