Version bump for release 0.1.7 RC 2

Support placeholders with #external declarations
This adds support for declaring predicates as placeholders through the “#external” directive in the input language of clingo. Placeholders are not subject to completion. This prevents predicates that represent instance-specific facts from being assumed as universally false by default negation when translating an encoding. This stretches clingo’s usual syntax a bit in order to make the implementation lightweight. In order to declare a predicate with a specific arity as a placeholder, the following statement needs to be added to the input program:
