Inconsistency in the use of $this and $PATH in sh:sparql vs constraint components

Peter reports that we use $this to point at value nodes in SPARQL constraints.
This should be fixed so that it refers again to the focus node, plus we should allow the use of $PATH when sh:sparql is used in property shapes.
Related is that we currently support a SPARQL result variable "focusNode" which has higher precedence than ?this for sh:focusNode in the results. I don't think this variable was ever discussed property and I want to delete it. - Related Actions Items:

Related notes:
RESOLVED 2017-02-15: Close ISSUE-230 by changing the binding of ?this from the value node to the focus node (section 5.3.1) and allowing the use of $PATH in SPARQL-based constraints. Remove the special handling of the result variable ?focusNode in SPARQL constraints. $this will become the sh:focusNode.
