cranlike 1.0.3

• cranlike now adds the size of the file to the metadata, in the Filesize
  column.

• cranlike can now add custom metadata. It has to be scalar currently,
  so it will be the same for all packages added at the same time.

v1.0.2

• create_empty_PACKAGES(), add_PACKAGES(), update_PACKAGES() and
  remove_PACKAGES() lock the DB, to avoid potential concurrency issues.
