Support added for Switch

[bzamfir]

Hi,

I needed support for kendo switch, so I added it myself with the code below

I'm not familiar with git, I'm using SVN for day to day work that's why I didn't created a pull request.

createBinding({ name: "kendoSwitch", defaultOption: CHECKED, events: { change: function (options, e) { options.checked(!options.checked()); } }, watch: { checked: CHECKED, enabled: ENABLE, readonly: READONLY } });

Please add it to next release.
Thank you
