When doing the MS Word to .odt conversion (in ezodf/scripts/converttooo.php) the OO executable is called with this parameters:

-writer -invisible -display

which requires an X Windows server to be installed on the server machine. Since having an X Windows server on a web server machine is pretty unusual (and can lead to security issues), there should be an option of running OO executable without the need for the X Windows server. In OO this can be done by not specifying the -display parameter, and specifying the --headless command line parameter.

So the possibility of controlling this parameters should be added to ezodf, and should be configurable in INI.

I propose to modify converttooo.php script so that it reads the command line parameters from an INI setting. In this way all other command line parameters could be adjusted if needed.
