Title: Fixing issue with AMD loaders

If you try to load ko validation via Require.js following error arises: "Cannot read property of 'rules' of undefined"
It happens because ko.validation is never set before calling registerExtenders() function. It makes no sense to
extend "exports" variable because it's just an empty object that nobody uses. The plugin should extend ko object instead.
