TYPO3 Core

The applied patch suggests some more features for the TYPO3 mailforms:

1) Have checkbox arrays available: Those are functionally similar to multiple select fields, but might be more convenient and familiar for many users out there. Regarding the rendering, they tend to be familiar to the already existing field elements of radio buttons. And of course there is a relation to the already existing single checkbox fields. So it's something in between - and quite useful, I think ;)

2) Possibility to configure a forms' reset button from within the wizard (as many editors might never use http://bugs.typo3.org/bug_view_page.php?bug_id=0000743 if they can't set it by using the wizard)

3) More configurability for wrapping submit and reset buttons.
