Ability to see new blocks and features for non-admin players

[Vialonyx]

Administrators can see the list of new blocks and tools added by the plugin by using the tab key on '/bb give' command but this is not the case for lambdas players.
Add a new command like '/bb show' which opens a GUI (or simple list) where we can see the new features (blocks and tools, categorized) added by the plugin.

We could use the 1.12 Recipes Book for that, unlocking the recipes after:

• for the stone blocks, the slabs;
• for the log blocks, the logs;
• for the tools: other tools? or the resp. logs & slabs for resp. the saw & stonecutter?
