[REVIEW 3-5][REVIEW 3-6] Data Form dialog layout (fdo#47947)

[Andras Timar]

Hi,

There were two problems with this dialog. First, buttons on the right
were not wide enough for some languages (French, German, etc.) Second,
the original developer used hardcoded pixel coordinates instead of
logical coordinates, and it resulted in suboptimal layout.
