Alex wanted these all in a nice spot so here you go.

1. Two recipes one page (self explanatory)

2. Showcase Page that supports tags. Example tconstruct:tanks example below
   

3. Mini Index page like there is for modifiers for other sections

Showcase page is implemented, will be in next build.

Two recipes in one page is not currently implemented, but we do support recipe with text.

Mini index is implemented

For things like modifiers, being able to load pages from all JSON files in a directory would be helpful for addons.

Update to say two of these are implemented in Tinkers Construct's book loader, and should be ported to mantle at some point in the future. Leaves just the page with multiple recipes.
