definitions from the selected datasource.

Report columns that display the fullname of users should behave
in a consistent manner with current functionality of tables, in
regards to sorting by each individual component of a name (first
name, middle name, surname, etc).
To facilitate this, instead of a hard-coded assumption that such
columns are always named 'fullname', table classes can now define
additional columns containing a users name.
This change contains most of the output components required for
reports such as exporters, templates, AMD modules.
Also included are classes within the component table namespace which
are required for extending the dynamic table API.
