Add Confirm Deletion Modal when deleting a recipe

[MichaelWashburnJr]

On iOS, if you slide a recipe in the list to the left and click delete... Or on Android if you click the delete button...

We should make an $ionicPopup to confirm the user wants to delete it. Text should read "Are you sure you want to delete {{recipe.name}}?" It should have a red delete button, and a regular/default colored cancel button.
