- Add EcoreSerializerBase.createTemporaryFileURI() and use it to fix generation of PikeOS vmit.xml configuration files
- Adjust other configuration generators (in particular: test cases for configuration generators) that relied on writing to pre-existing resources in Eclipse bundles (which, however, only worked in the developer installation and never in the pre-compiled RCP)
- Hence, remove output placeholder files that are no longer required.
