Title:
  Warn admins if session.entropy_length is < 16

Status in Mahara ePortfolio:
  Fix Committed

Bug description:
  The session.entropy_length variable in php.ini controls how much
  entropy is used when generating session keys:

    http://nz.php.net/manual/en/session.configuration.php#ini.session
  .entropy-length

  OWASP recommends that session keys contain at least 128 bits (16
  bytes) of entropy so we should print a warning on the admin page to
  let admins know that they should set this variable to a larger number
  (it unfortunately defaults to 0).
