- ece-install will now set up a cron job for deleting old thumbnail
  cache files.

  The reason for this being inside ece-install::content-engine and not
  in a file (removed from the git tree in this commit), is that the
  directory is set depending on the fai_ parameters (with a sane
  default good for most folks set, of course).

  This cron job assumes that the ECE
  com.escenic.presentation.servlet.multimedia.CacheFilter servlet
  filter has been configrued to write to the path below in (each of
  the publication webapp's) web.xml

- removed etc/cron.d/remove-old-escenic-cache-files from git tree, see
  above.
