Support responseTime setting for JSONP.
Added breaking test for #114 (note, that PR will be close in favor of one from this local branch)
Added missing semicolon
Fixed merge conflicts in test.js
Merge pull request #172 from appendto/freedmagnet--jsonp-responsetime

Recognize responseTime option for jsonp requests
responseTime setting can be set with a min and max value, mockjax will choose a random timeout between min and max
using jQuery.isArray instead of instanceof Array

returning null from parseResponseTimeOpt function if its not a number
abstracted the min and max values into variables for maintainability. I'm not sure if this is the Qunit way or not, but it seems fine to me
