Changeset 5404 for branches/HeuristicLab.Hive-3.4/sources/HeuristicLab.Clients.Hive.Slave/3.4/ConfigManager.cs

• changed the workflow of aquireing a new job from server.
  • if a job is available for calculation, the slave receives the jobId already with the heartbeats. The job is then exclusively assigned to this slave.
• extended the metainfo for a slave by OperatingSystem and CpuArchitecture
• enhanced the way plugin-dependencies are discovered by using the types used by XmlGenerator. Now only mimimum amount of plugins are transferred.
• selection of waiting jobs now consideres assigned slave-group
• more unit tests for service
• added unit tests for experiment manager
