Reviewers: rjrjr, Description: It turns out that previous patch was not enough. In new one instead of preventing failing when no owner or field found, we disable assigning to fields and support for event handlers at all. However we can not disable them globally, for all UiBinder templates, we should do this only for template under design (because other templates may be used on it). So, I've changed a little way for choosing DesignTimeUtils implementation.
