Both objects and create activities will now go through the common pipeline and will be validated. Objects are now created as a side effect of the Create activity, rolling back a transaction if it's not possible to insert the object.

This module looks at an inserted object and executes the side effects that it

implies. For example, a `Like` activity will increase the like count on the

liked object, a `Follow` activity will add the user to the follower

collection, and so on.
