ooxml: export date controls properly

Export date controls as ooxml Standard Document Tags (SDT) instead
of replacing them with plain text.

SDT date controls contain the date in ISO format as an attribute of
<date> tag, a custom date format that can be specified by the user
in the <dateFormat> tag and the date formatted in that custom format
in the <w:sdtContent> tag.

The unit test testFormControl from ooxmlexport suite was removed,
it only checked if the date control was exported as text and it
obviously fails now. A new test that checks the values of the
exported control was written instead.

A pair of date format functions were added to datetimeutils.hxx.

TODO: to avoid supporting all the posible custom formats that can be
specified in the <dateFormat> tag, it is forced to dd/mm/yyyy on
export.
