RSS improvements

Date: 28.2.2013

RSS feed is improved. We have added the flag important that lists all orders that were not inserted programatically. We have also set new behavior for missing values. If no flag of commodity is set, all commodities will be shown now.

Default RSS feed without parameters now contains all commodities with flag important on all guarantee systems and rings. Default feed is available here: http://www.carbonplace.eu/rss
