Title: Enable deep cloning when using nested models

I noticed this topic has been covered to some degree in #155. But it was targeted at any nested attributes. This specifically targets the use of nesting models within the attributes of other models. Which as far as I've figured seems to be the sanest way to deal with certain types of relational data.

Deep cloning is enabled by passing `true` as the first argument to the clone method on a model or collection.
