Having the ability to customize the scheduler toolbar (or header) via template will increase its flexibility. In addition it will allow for rendering improvements while maintaining backward compatibility via the templates.

While it may seem like a straightforward task, it requires at least:

* extracting toolbar commands to be callable from client code
* the ability to iterate trough the currently viewable views to set the buttons (to match the userselectable property)
* per button setting ala ListBox button settings
