Possibility to specify `scope` in `property.access`

[sirex]

It should be possible to specify scope in property.access column in order to make property visible only if scope is given.

For example:

model	property	type	ref	access
		sql
City			id
		scope	names	protected
	id	integer		protected
	name@lt	string		protected, names
	country	ref	Country	protected
	country.name@lt	string		protected, names

Here, you can only access name@lt and country.name@lt if @names scope is explicitly given.
