Issues with Userforms #45
Description
When using with User Forms Silverstripe bootstrap forms adds form-controls to the fieldset and header fields in the forms, which brake it.
<fieldset class="form-step userformsstep form-control viewed"
<h3 class=" FormHeading form-control" id="UserForm_Form_EditableFormHeading17" type="hidden" data-id="EditableFormHeading17" name="EditableFormHeading17">CONTACT INFORMATION</h3>
It also needs to add the btn class to the buttons.
