Option to preview needed items for schematics in your inventory, before building

## Describe your suggestion
When you build and the build fails because you don't have all the blocks, adding a ghost-like semi-transparent texture of the needed items in your inventory would be nice.

## Settings
`#previewBuildItems`

## Context
Most users are confused when building fails, adding a visual way for them to understand how would be immensely helpful in reducing the amount of stupid issues that are created.

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have not used any OwO's or UwU's in this issue.
