Title: Update jasmine from the future for better stack trace

Using assert in Jasmine 1.3.0 doesn't give you a proper stack trace. However, this is fixed in 1.3.1 but it's hard for us to bring in all the changes. So I'm brining in a change to fix this particular problem. For posterity here is a link to the code I copied:
