In order to rename a namespace manually you will have to:
  * Rename the folders that represent the namespace in:
    * ''data/pages''
    * ''data/media'' (if this exists)
  * Remove metadata for the namespace under ''data/meta''
  * Remove attic data for the namespace under ''data/attic'' (or move that over as well, if you want to preserve old versions)
