BookPress

Squished those bugs and updated code! The code has been almost entirely rewritten and improved 500%. There should be no more bugs and 1000% more awesome.

Other changes include...

You can now press multiple items in your presses. Throw multiple book & quills/empty maps in with one you want to copy and it'll convert them all!

This build has not been tested for Spigot builds older than 1.13, but there isn't any clear indication that it should not work.
