Replace buttons added as widget_button with widget_container buttons in Catalog/Product/Edit

[B3Hana]

Description (*)

It is currently not possible to add, remove or change buttons in the catalog/product/edit form without overriding/changing the edit.phtml, as all buttons are added as widget_button and then rendered by reference.

With the Mage_Adminhtml_Block_Widget_Container->getButtonsHtml() it is possible (but definitly needs some more events) to change the buttons without overriding the template itself, via an observer. (controller_action_layout_render_before_adminhtml_catalog_product_edit)

Manual testing scenarios (*)

Listen to the event and add a button to the product_edit.
(Mage::app()->getLayout()->getBlock('product_edit');)

Questions or comments

I changed the internal layout id of the close button from "back_button" to "close_button" and the "save_and_edit_button" to "save-edit_button" as this are the constants provided by the widget_container class.
I didn't notice a problem, but I probably didn't check every possible configuration there is.
