Re-factor matchable to reduce complexity

This solution is much cleaner than what is in StdMatchableTranslator.
Over 90% code coverage on it - utilizes a callback to retrieve DataType
and PolicyTypes. Support for missing timestamp TOSCA type. Also can
do a better job differentiating between a property contained in the policy
vs a schema.

Changed StdMatchableTranslator to utilize these classes. And removed the
old spaghetti.

Added some JUnit coverage for ToscaPolicyTranslatorUtils.

Removed duplicate code in the XACML Native Exception classes.
