MP2-422: Improved logging in DirectoryUnfoldBlock
MP2-422: let ImporterWorkerNewGen send all the system messages that ImporterWorker sent except for ImportStatus (to be replaced by ImportProgress)
MP2-422: Implemented ImportProgress message
MP2-422: Improve Exception handling in ImporterWorkerNewGen (loading persisted ImportJobs from disk)
MP2-422: ImporterWorkerNewGen: Implement listening to system messages and scheduling of regular refresh updates
MP2-422: Set importJobInformation.State = ImportJobState.Active for all Scheduled ImportJobs to simulate the behavior of.the old ImporterWorker. ToDo: Remove this and all usages of importJobInformation.State once ImporterWorkerNewGen is ready because in ImporterWorkerNewGen all Imports are "active" at the same time.
MP2-422: Solved a bug in SharesHelper.BestContainingPath: If there were two paths in the enumeration that were the same or parent of the path we were looking for, and the first match was a better one than the second, we erroneously returned the second one because the length of the first one was not noted as bestMatchPathLength
