Add tools database

[seyfeb]

Analogous to an ingredient database, see #135, a database for tools required for a recipe should be introduced.

This would allow for enhanced filtering of recipes, like

• "Show all recipes that use a cookie cutter"
• "Show all recipes that need only one pan"
• "Hide all recipes that would require an oven"
• etc.

A similar structure for the database, management, UI, ... as for the ingredients could be used.

Here is some JSON based on the discussion #1874:
