Add tags for "allergens", "additives", "diets" to project template at Coocook.org

[dboehmer]

At Coocook.org the Project Template offers some basic data which can be imported into new projects as a good starting point. We'd like to have a reasonable list of allergens and additives as tags.

How to do that

1. register account at https://coocook.org/register
2. request editor access to the Project Template with your Coocook username in this GitHub issue or via e-mail to coocook@lists.coocook.org
3. add and revisit tags at https://coocook.org/project/Project-Template/tags

Acceptance criteria

• at least 10 tags in tags groups:
  • allergens, e.g. peanuts
  • additives, e.g. coloring agent
  • diets, e.g. vegan
• correct English terms (at the time of writing non of the team members is native English speaker)
