Miklos Vajna 9a76be53df sw content controls, picture: add LOK API 
- send a LOK_CALLBACK_CONTENT_CONTROL callback with
  action=change-picture when a file picker should be shown

- extend lok::Document::sendContentControlEvent() to be able to replace
  the placeholder with the selected URL

- update gtktiledviewer to work with these
