objectstore: option to clone object on commit

Browse source 
Add a new `clone` parameter to the `commit` method on `ObjectStore`
that when used will clone the object to the store instead of using
the `store_tree` method which moves the object and resets it. This
is the first step of removing copy-on-write support from `Object`.
