Datepicker does not work in IE from local intranet due to security zones

[dkl]

Steps to reproduce:

1. Disable javascript in IE in internet zone (Internet Options -> Security -> Internet -> Custom Level... -> Scripting -> Active Scripting: disable)
2. Make sure javascript is enabled in local intranet zone (Internet Options -> Security -> Local intranet -> Custom Level... -> Scripting -> Active Scripting: enable)
3. Open page with any datepicker in IE from local intranet zone
4. Datepicker will display when clicking into textbox, but you are unable to select any day or move to another month.

Why this happens

Datepicker creates content of calendar as HTML string (function _generateHTML). For each clickable element (e.g. day), an onclick attribute with javascript code is generated. When finally adding this HTML to the DOM tree, IE thinks this is script from internet zone and disables any javascript in it.
