[#805] project folders wip
[#805] indentation fix
[#805]

* Made survey groups hierarchical. A survey group can now have a 'parent' survey group
* Added a 'projectMigrations' endpoint to the testHarness which splits surveys in non monitoring survey groups into their own survey group. Non monitoring survey groups can contain at most one survey.
