IE7 and IE6 Support

Right now IE7 and IE6 throw script errors due to JSON.stringify and querySelector. json2 provides the stringify method and polyfill-queryselector will provide the querySelector method. I also have a pr with jasmine to address two issues with script errors in boot.js but once these two small pr's are merged, both IE7 and IE6 will be able to run Jasmine tests no problem. I've got this wired up locally and it works great.

The reordering of package.json was done by npm after installing the two new deps.
