save custom crafting recipes

I think that it is a good idea to let players save recipes they use frequently (plus there own custom recipes e.g. fireworks) in a new tab in the recipe book.  This would let players find certain recipes quicker or just let them craft that item in bulk quicker.

(Side note I think bows should stack while in the crafting grid if they are undamaged and unenchanted to allow easy crafting of dispensers).
