[O] [bug?, ox-odt] Format DATE

[Rasmus]

Hi,

ox-odt.el ignores `org-export-date-timestamp-format'.

Instead, it uses a variable `org-odt-use-date-fields', which maps
/all/ dates to the styles "OrgDate1" and "OrgDate2".  I'm not sure if
these are meant to be customizable or not.  In LO I'm able to change
the style by clicking on the timestamp so probably the style has to be
specified that way, somehow.

Unfortunately, the undocumented `org-odt--format-timestamp' does not
seem to support alternative formats, but again, this may be due to
fact that dates are formatted in LO.

I /might/ have time to look at this myself over the weekend, unless
someone knows how to fix it.
