* Tweak style of quantity label in output box to be more visible
* Move data files for all mods under a directory for the specific
version of the mod
* Add a `silent` property to the base model to prevent models which
shouldn't be observed from emitting events
* Change the term "itemSlug" to just "slug" across the board
* Change all models so that they don't require their parent in their
constructors and so that they don't automatically add themselves to
their parents lists
* Remove a bunch of unnecessary event triggering
* Tighten up access to various lists of children across all models
* Refactor the guts of the V2 parser into an abstract base class so
it can be used for other parsers in the future
* Remove a number of unused methods
* Refactor location of all data files to include a subdirectory
for the mod version
* Update the BaseModel class to allow models to load themselves from
any text file (whether JSON or CG)
* Refactor ModPack & ModVersion to move the laoding functionality in
one into the other (and use the new stuff in BaseModel)
* Move the parser versions into a new subdirectory which allows for
future additional parsers
In addition to the new script, this changes the V2 parser to be able
to continue past the first error found so that as many errors as
possible may be displayed.
* Revert the local storage change as it ties model objects to global
state and makes testing impossible. It will be necessary to redo
that feature differently
* Refactor the parser versions to move V1 into its own set of files
* Rewrite the crafting algorithm to recursively find all the steps
involved and then resolve how many times each needs to be run.
* Update the base controller to debounce calls to refresh
* Fix a few erroneous recipes for IC2-Classic
