add recipe interaction needs update

[gidden]

Currently, you can press "Add Recipe" any number of times and it will add blank entries into the recipe list. Those entries are not selectable afterwards.

I think the best way forward is to refactor the interface to use a stage-and-add pattern (similar to git commits, for instance). In the simplest implementation, two separate buttons are needed: "New Recipe" and "Add Recipe". Clicking "New Recipe" will present the same interface that "Add Recipe" currently does. However, it will keep its recipe information "local" to what's currently on the screen. When the user is content with recipe the have built, they can then click "Add Recipe" to add it to the list of available recipes.
