Allow skills to mark response as final to prevent going next

[manthanhd]

Something like:

response.message = new SingleLineMessage('We\'ve mailed the product to you');
response.final();
return next()

[manthanhd]

I should also be able to mark response as final without providing a message in which case up to previous skill's message is considered.
