LP2095532 Ctrl+arrow creates only one new MARC row

In the MARC rich editor, call preventDefault() and stopPropagation() on
keydown handlers when pressing Control + the up or down arrow to avoid
creating duplicate copies of the current row (due to similar handlers in
both the editable content and rich editor components).

See also bug 2084199 for related keyboard operation errors prior to
3.13.6 and 3.14.1.
