This introduces the new crafting page design featuring a new vertical
layout and list display of all crafting steps. It also makes it easy
to move items between the have/need sections and even from each step
into your inventory (causing a new crafting plan to be created which
doesn't plan on making that item).
* Convert the `BaseController.hide` and `show` methods to be much
more robust in the use of CSS transitions (using a timer in case a
transition doesn't actually fire).
* Change `hide`/`show` to use events for communicating animation
state instead of callbacks
* Convert several controllers to fire events for communication with
parent controllers instead of accepting functions.
* Rewrite the `CraftPageController`, `CraftPage` model and related
Jade/SCSS files to implement the new design.
* Alter the `InventoryController` and `StackController` to allow a
variety of action buttons, and for the events from those action
buttons to bubble up to parent controllers
* Add the `StepController` and its related model, template, and style
sheet as part of the new craft page.
* Tweak the `ItemSelectorController` and related files to allow for
a variety of styles for the launcher button
* Create the SlotController and refactor it into the various places
where a crafting grid or crafting output is displayed
* Update the Recipe model to allow each "input" stack to retain the
count indicated in the data file. This required changing how a few
other classes interact with it in order for them to get the full
stack back again for each input (instead of just getting the item
slug)
* Update the ModVersionParser to allow for full stacks to be given
as input and refactored common code out for handling input/output/
tools stacks
