R9.3, R9.4: AutoFilter without the header query (GitHub #4); paste on Windows

Patch 0053: under LOK, Calc takes the first row as header instead of
asking asynchronously; the worker closed the query and crashed.
Patch 0049 includes doc.hxx (gcc on Linux did not build it).
arboard read a missing HTML clipboard format as an error on Windows;
the clipboard checks the format first, and paste errors show the
whole chain. ElyTable tests compare CSV and selection text the
platform's way (P3-09).
