Modified Network#makeRequest and Request constructor to ensure that they throw runtime exceptions instead of normal exceptions.
Fixed Network tests and examples to conform to RuntimeException changes.
Fixed Janeway project and DefectTracker project controllers, etc to conform to RuntimeException changes in Network project.
Fixed TestRequest#testRequestSetRequestBodyNullPointerException so that the exception is once again properly tested for.
