    exchange update rate policy
  - the user will be notified if a new version is available

    the number of supported exchange rates (ascending and descending),
    and by alphabet (ascending and descending)

  - using Apache's commons-cli 1.4 in order to parse the command line args
  - Exchange Rate update engine is being used by both the GUI and the CLI
  - added the removeTagsBeforeParsing property for the exchange rates filter engine

    improve the sorting of the exchange rate filters
  - updated the user-agent list that is being used by some exchange rates filters
  - many smaller internal improvements (applying common design patterns)
