Create settings model and cell model

Created a model for the Settings data stored in the plist. Also created an abstract class for the table view cells so cell subclasses can be exposed and manipulated through one class
I'd avoid adding a string to this array. The expectation is that it should only contain settings item model objects.

Instead, just create a concrete subclass of a settings item for the version and add a new instance here. The cell and/or table data source itself can contain the code that pulls the version out of the plist and sets it as the detail label.
