Export: allow exporting of additional properties

This change introduces an additional property that may be set on a
target to allow additional properties to be exported. Normally only a
limited number of properties are exported.

Additional properties may be exported by simply setting the
`EXPORT_PROPERTIES` property on a target that is exported.
