* commit 'c292ee522774f9b533199d8cfa66e2b0d97670e8':
  Fix migration for documents (drag n drop field was added to document content type and is now named c4m_document instead of the c4m_media field)
  Migration of minisite pages
  Update import to create wiki pages instead of minisite masters
  Added complete function that updates the timestamp of the automatically created (activity) message when a comment is migrated.
  Updated the timestamps of the messages so they match the node creation dates.
  Changed the import of blog posts to discussions.
  Build in a file migration mapping so we don't copy the same inline files more then once. This also avoids duplicate files in the file_managed table.
  Enable manual path aliases to be set during migration
  Fix: Warning when $items[0] is empty
  Disable revisions on book pages (book_node_presave sets revisions to TRUE)
  Cleanup code
  Set revisions to FALSE before starting the migration
  Add dependency to Tasklist migration, to prevent tasks being imported before tasklists are there.
  Add mapping for non-ISO country codes. Only discovered UK => GB for now.
  Use the filename from the full path instead of the filename column. If a user uploaded a file "photo.jpg", which already existed, it was renamed to "photo_0.jpg", but the filename still remained photo.jpg.
  Added missing info about install or upgrade.
  Update of the readme.
