jQuery parseJSON automatic date conversion for Asp.net and ISO date strings

This one's quite common. You asynchronously communicate (a.k.a. Ajax) with your server and get JSON data in return. You most probably use $.parseJSON() on the client side which actually parses JSON string and returns an object. We've all used that. But (yes, there's always a but) there's a catch. There's no defined standard for date serialization, so jQuery will not parse your dates back to dates. What the heck even native JSON parser (these days supported in all major browsers) won't do that. So you have to do it yourself. Manually. Or, modify default jQuery functionality a bit and get it done automatically.
