Message:

#1888:

• WorkerRole of Slave now logs all exceptions during startup to the blobstore (slavelog).
• The PluginManager throws an exception during CheckWorkingDirectories() (Save method) which will be caught now, preventing crashes in Windows Azure.
• "db.DeferredLocal = false" has been removed to prevent loading bugs.
• HiveScenarioManager doesn't crash anymore, if he can't find an algorithm within a job during retrieval of the run results.
