* Introduce recipe book functionality
The recipe book helps especially new players. Missing it gives the
impression that cuberite is not as advanced as it is.
The handling of the recipe book uses the following functions:
- Unlock Recipes
(https://wiki.vg/index.php?title=Protocol&oldid=14204#Unlock_Recipes) to
make recipes available and show the notification for new recipes.
Initialization is done on player login for known ones, the update is done
when new items are discovered.
- Craft Recipe Request
(https://wiki.vg/index.php?title=Protocol&oldid=14204#Craft_Recipe_Request)
when the user selects a recipe from the recipe book to fill the slots.
Known recipes are initialized on player login via `Unlock Recipes` with
`Action` 0.
As soon as a new recipe is discovered this is added via `Unlock Recipes`
with `Action` 1.
To be able to know and recognize new recipes the player class is
extended with `KnownItems` and `KnownRecipes`. As soon as a player
touches an item this is compared to the list of `KnownItems`, if the
item is unknown the recipes are checked for this item and the other
ingredients are checked with the list of `KnownItems`. If a full match
is discovered the recipe is unlocked with the client and stored in the
`KnownRecipes`.
To unlock recipes the recipe ID is sent to the client. A mapping file
(for protocol 1.12.2) translated the minecraft recipe names to ids. The
crafting.txt is extended with and minecraft recipe names is possible.
Limitations:
Only a single recipe is added to the crafting area. Multiple clicks or
shift click does not increase the number of builds.

- Some linting
- Extract loading of recipe specific protocol mapping into a function
- Build `RecipeNameMap` only once
- Use `std::optional`
- Extract `LoadRecipe` from `Window`
* Start to implement new suggestions
* Update with suggestions from @peterbell10
* Some minor cleanup
* Update protocol packet IDs
* Remove unused include
