Remove 'Book and Quill' recipe

It is no longer required since we provide an 'Ink Sac' recipe. In
Minecraft 1.12, there is only one source of black and that is from
an 'Ink Sac'. There is no separate 'Black Dye'.

 Item | Recipe | Description
 ---- | ------ | ----------
-Book and Quill | ![Crafting table: shapeless: book, stick, black dye -> book and quill](https://raw.githubusercontent.com/ACascarino/vegcraft/master/img/book_and_quill.png) | Original book and quill recipe used feathers and ink sac; substituted a stick and black dye for a "pen" theme
 Blaze Powder | ![Crafting table: top row: glowstone dust, gold nugget, glowstone dust; middle row: nether wart, gunpowder, nether wart; bottom row: glowstone dust, gold nugget, glowstone dust -> blaze powder](https://raw.githubusercontent.com/ACascarino/vegcraft/master/img/blaze_powder.png) | Original blaze powder is produced from blaze rods, a drop from Blazes - went with a "firey gold powder" theme
 Blaze Rod | ![Crafting table: top row: -, gold nugget, -; middle row: blaze powder, stick, blaze powder; bottom row: -, gold nugget, - -> blaze rod](https://raw.githubusercontent.com/ACascarino/vegcraft/master/img/blaze_rod.png) | Original blaze rods are a drop from Blazes - flipped production so powder is now produced first and rods are constituted from powder.
 Ender Pearl | ![Crafting table: top row: quartz, cyan dye, quartz; middle row: quartz, bottle o' enchanting, quartz; bottom row: quartz, quartz, quartz -> ender pearl](https://raw.githubusercontent.com/ACascarino/vegcraft/master/img/ender_pearl.png) ![Furnace: end stone -> ender pearl](https://raw.githubusercontent.com/ACascarino/vegcraft/master/img/ender_pearl_smithing.png) | Original ender pearls obtained from endermen - went for a "magic glass orb" theme. Requiring Bottles O' Enchanting forces it to be a late-game item. After you reach the End, ender pearls are plentiful, so made the smelting recipe to reflect that.
