Unit tests and cleanup
- GalaxyWorkflowEngine: wait times are now configurable and are set to zero for tests (see the GalaxyWorkflowEngineTest.runWorkflowTest method).
- WorkflowEngine: removed the configure methods. (Also for DemonstrationWorkflowEngine[Test], DummyWorkflowEngine, GalaxyWorkflowEngine, and MolgenisWorkflowEngine[Test].)
- BaseWorkflowTest: test the getAllInputEntries method and the [get|set]AutomaticDownload methods.
- FileUtilsTest: added test for the createTemporaryFileWithPrefix method.
- BaseWorkflow: fixed typo (inputFiles instead of inputsFiles).
