- modified RnaSeqDgeExample.
- switched to latest version of the RNA-Seq EdgeR workflow.
- again ignore two unit tests: DefaultWorkflowEngineFactoryTest.testGetWorkflowEngine and WorkflowEngineTest.testGetWorkflow.
- added debug parameter to Galaxy configuration.
- pass null as API key to the GalaxyConfiguration.buildConfiguration method to retrieve it from the properties file.
- pass null properties file path to the GalaxyConfiguration constructor to postpone reading properties.
- GalaxyConfiguration.getGalaxyApiKey: try reading a server specific API key first, before reading the general API key.
