reverse order of resource version array, so the last value is the last in the array.
The idea is that a specific version number is unchanged when more versions are added to the resources array
create a folder for sid specific tmp, and then delete entire folder when sid is deleted on timeOut
added Collecion.rmdir() which removes a children from a Collection (not a delete, as the change is versionned)
added noversioning on database, which is used to cancel resource versioning completly. used on /tmp database (no undo on /tmp!)
