Title: Add ko.utils.wrapObservable 

This is the reverse logic of unwrapObservable. It allows you to set properties whether they are observable or not.

Usage:
```
var viewModel = { min: 0, max: ko.observable(100) };

ko.utils.wrapObservable(viewModel, "min", 10);
ko.utils.wrapObservable(viewModel, "max", 90);
```
