fix the repr for Recipes with new schema

I forgot to update the repr of the Recipe class to reference recipe_body
instead of recipe.
search: Added initial Search functionality

Does not include labels yet
If you search for time <= N, it will not show recipes without times.
  **may be DB specific!!
remove label redirected to invalid target

Whoops. remove_label_from_recipe should redirect to "edit_recipe" not
"show_edit_recipe".
