sw content controls, date: add current date handling

While working on the DOCX import for dates, it turns out there is a need
to store the selected date in machine-readable format as well. This is
useful, because once the timestamp is formatted, the user is allowed to
hand-edit the result, so otherwise the selected date would be lost.

This commit adds:

- doc model & UNO API

- click handler (store the selected date, default to the current date in
  the date picker if possible)

- ODT filter

- DOCX export

And tests for all these.
