Added console logging in the grid write callback functions. Removed grid sorting, it is done on the server side. Alert popup for block row edit functions. Better grid live updates. In recipe and product print show the whirlpool time. The checklist now shows misc ingredients added in the mash. Show hops added in the whirlpool. Most ingredient names are now quoted.
