Updated the Console methods under both Runtime and Debugger.

Method names: Runtime.evaluate, Debugger.evaluateOnCallFrame

To facilitate these, converters now exist for both Results/Values gotten from V8 via the debugger into Inspector Values and Error messages into Inspector Error objects.

Side Effect: Runtime.getProperties had to be updated to handle new types of values the Inspector is now slinging its way.
Breaking on an Exception now provides a reason.
