Allows modders to set recipes for rocket launch products.
This in turn allows modders to gate those products via technology or other means.

Example:
{
type = "recipe",
name = "arp-launch-productivity-module", -- start with "arp-launch-" followed by the id of the item to launch
ingredients = {{type = "item", name = "productivity-module", amount =1}},
results = {{type = "item", name = "productivity-module-2", amount = 1}},
enabled = false,
subgroup = "space-related",
category = "advanced-rocket-products" -- required
}

Note: You don't have to set the result in the "rocket-launch-product" field of your item prototype, but it will work if you do and may be useful for player's who use factory calculators, as they won't properly account for the recipe otherwise.
