Better Chiseled Bookshelf

This might be the final version of this mod, so I added a couple things

• More config options
• Option to filter allowed/denied blocks in the path to the shelf
• Changed the way the table searches for shelves. Might make it a little faster
• Made it more bearable to use in a size of 15+

After this, the mod will only recieve update to newer versions of the game and bug fixes (if needed)

Might add new stuff if something comes up in mind
