Import internal type systems by name instead of location

[reckart]

Describe the refactoring action
Import internal type systems by name instead of location. E.g. BasicTypeSystem.xml imports RutaInternalTypeSystem.xml by location instead of by name.

Expected benefit
The uima-bnd-plugin is unable to handle import-by-location and issues a warning whenever such imports are hit. This happens a lot with ruta projects.
