bug #988 [AddLines] Fix update process to send changes to RecipeUpdate vs make them immediately (weaverryan)
This PR was squashed before being merged into the 1.x branch. Discussion ---------- [AddLines] Fix update process to send changes to RecipeUpdate vs make them immediately Hi! This was an oversight when I create `AddLinesConfigurator`. During `recipes:update`, the purpose of the `update()` method in each configurator is to record what the "original" contents of a file would look like from the original recipe & what the "new" contents of a file would look like with the new recipe. Then, LATER, the patcher system creates a diff from these. The `AddLinesConfigurator` was going rogue and updating the files immediately, which caused the "patcher" system later to explode because this file was unexpectedly already modified. The changes are less drastic than they look, as code needed to be moved from some public methods -> private methods. Cheers!
