MenuGenerator additional features

This should probably be unrolled into separate issues later, when they are tackled. Adding the epic label for that.

• Reroll a single recipe within the same context (give a recipe list and index, and receive the new recipe or new list of recipes to use in the template).
• Select number of recipes of each type to have a balanced menu (number of each type would be used as a target instead of a total number of recipes)
  • Potential problem: rerolling a single recipe of a type when the type cap is reached.
• Swap recipes up and down (reorder list: move up, move down, maybe also move to top and move to bottom)
• Update page parameters upon menu generation to be able to share/bookmark a menu link (e.g., the url params might have the recipe ids)
• Print recipe to PDF
