Clarify scope of Application Components

The current spec (v1.0) defines Application Components as:

"a collection of code, resources and metadata that provides a set of related services or functionality. Examples include a Java library, or a PHP module."

We need to clarify that Application Components may also include data (i.e. a dataset that needs to be loaded into an SQL table in order for the application to work) and identity (i.e. a set of account information that needs to be loaded into an identity store in order for the application to work).
