Add files needed for Ext.Test locally, instead of loading them from the ExtJS CDN.
Add Jasmine, and split test harness into two frames: one which shows the Ext.Test harness, and the other which shows the Jasmine harness.
Add Operation objects, for passing along the options, and reading back the result of operations between Models/Collections and their proxies.
Few tweaks to Collection#load() documentation. Need to add unit tests.
