cm serverimport flushes more often

Especially when importing huge content-sets in a multi-site environment, you may have observed out-of-memory-errors.

To reduce the memory consumption, an internal optimization has been applied to cm serverimport, so that it flushes changes more often to the server while updating the imported content.

cm serverexport: Base Directory Created On Demand (Again)

Since several releases, when invoking cm serverexport given a base-directory that does not exist yet, no exported contents were available afterward (but serverexport reported successful export).

This has been fixed. The folder is now created on demand again, if not yet existing.
