XSL now handles the new ingredients model in XML. XSL now looks up inredient names from a centralised list in the XML. Ingredients are indexed twice, 1) in a "flat" alphabetical list of all ingredients; 2) in a categorised list (when the categories are given). Actual heading/formatting of the subindices will be addressed in issue (Note that the XSL code can probably be optimised further.)
