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
Merge branch 'master' of github.com:appendto/jquery-mockjax
calling parseResponseTimeOpt for jsonp requests so they will work with variable response times too
Merge pull request #170 from dotDeeka/master

Allow a min and max to be set for responseTime to more accurately mock the variable response times of an actual server.
