  Remove the clientVersion parameter from the format utils.
  
  clientVersion was only useful for intitial validation of formats and not
  required for queries.  Only use the client version and caps structure to
  validate if a format is available and then trust that it is supported past
  the validation layer.
  
  Fixed some inconsistancies between tables such as missing formats or
  incorrect load functions in the ES3 tables.
