sw content controls, date: add LOK API

- send a LOK_CALLBACK_CONTENT_CONTROL with date=true when entering a
date content control

- extend lok::Document::sendContentControlEvent() to be able to set the
date of a date content control (after the client's date picker is
closed)

- update gtktiledviewer to work with these
