If outname is given, it is either '.off' or '.gts' or a filename ending

be used with extension changed.
If the outname file exists and its mtime is more recent than the stlname,
the outname file is considered uptodate and the conversion programwill
not be run.
The conversion program will be choosen depending on the extension.
This uses the external commands 'admesh' or 'stl2gts'.
The return value is a tuple of the output file name, the conversion
program exit code (0 if succesful) and the stdout of the conversion
program (or a 'file is already uptodate' message).
