Add accessors to Type.create() and Type.add()

The release makes it possible to create user-defined accessors for use with Type.create() and Type.add(). The getters/setters so defined will manipulate data in an off-result data object, which may optionally be given a reference in the result.

This can be used to hide the actual value and force access to go through a validating accessor, for example, or it can be used to create read-only properties for which the storage form of the data is unretrievable, even with Object.getOwnPropertyDescriptors()
