[TASK] EXT:form - Set proper default values in form wizard

This patch sets proper default values for all elements in the form
wizard. The available elements and fields have been sorted by necessity,
i.e. most often used elements have been moved to the top.

The type of the TEXTLINE element can now be modified. That way the editor
can create HTML5 input types. The avaible input types within the wizard
have been streamlined to not show duplicate elements like checkbox or
radio (which are elements on their own). The right side of the wizard
has been optimized to not validate elements according to their HTML5
attributes. Last but not least the predefined email element is now of
type email.
