* InputButton
*
* This button type renders a HTML tag <button> and takes the HTML attributes
* name and value as additional attributes to those defined in AbstractButton.
*
* Since we no longer want to have any <input type="submit" /> in the TYPO3 core
* you should use this button type to send forms
*
* EXAMPLE USAGE TO ADD A BUTTON TO THE FIRST BUTTON GROUP IN THE LEFT BAR:
*
* $buttonBar = $this->moduleTemplate->getDocHeaderComponent()->getButtonBar();
* $saveButton = $buttonBar->makeInputButton()
* ->setName('save')
* ->setValue('1')
* ->setIcon($this->iconFactory->getIcon('actions-document-save', Icon::SIZE_SMALL))
* ->setTitle('Save');
* $buttonBar->addButton($saveButton, ButtonBar::BUTTON_POSITION_LEFT, 1);
