changes from Miner59 including:

- no unknown items shown when recipes have "group:..." inside, there is then instead a button displayed which shows all items in this group when you press it.

- added a new feature to show the complete list of items you need for a item. For example: output: default:bookshelf,
then it shows: 6 "group:wood", 27 "papyrus". This feature was the most work. I hope it works, but no guarantee.(It could lead to huge for loops which it doesn't exit when recipes are very compex. Also needs to be tested which more mods.)

- you can direct change from last page to first page and from first page to last page now

- added a button to exit the formspec

- crafting recipe for craft guide changed to use group:stick

- crafting recipe for craft guide pc changed to use just the recipe with stone slabs
