Rework Writting Book

Rework the writting book to add :

- Bold, Italic, Underline, Size text, Alignement, Better color system, List, (Selectable with a column at the right of the book) Maybe the possibility for adding pictures ?, Infinite number of pages ?... and many other things like you can find in Word office (Microsoft).

I just have a simple dream it's to be able to write a story directly in minecraft set up in my castle (singleplayer or  multiplayer) and to export this in differents text file format for publish it later.

Thanks :D
