FEATURE/UPDATE: 2012.6 Run Imports As Background Job

Now you can save more time and continue working in your admin WHILE you have an import running! That's right, no more waiting around for the upload to finish :)

Imports and exports will now run as background tasks, and the background jobs UI has been updated to show information about import/export progress in real time.
The attached video is the best way to see it in action, but here's some screenshots. The design is not set in stone by any means so feel free to give your feedback.
