Changeset 9469 for branches/HivePerformance/sources

Message:

#2030

Task- and Plugin-data is stored in the file system instead of the database.
This is accomplished by the Filestream feature of the SQL-Server.

Fixed bug when Heal-Group does not exist.

Note: SqlServer configuration changes are necessary for Filestream feature
