B13767 this fix prevents marking elements with class .btn to required color, which aren't given from forms itself (all form buttons are 'button' tags).

Also implemented new CSS lines to overwrite specific bootstrap.css rules for the datetimepicker (arrows are higher positioned, which looks better than before)
