Title: Don't clobber filtered content from other plugins

Currently some of the functions in this plugin attach to MarketPress filters, but assume that there is no content already. They don't pass the current filtered content into the function, thereby clobbering anything that other plugins may have added via the same filter. The attached patch fixes this.
