Run VOXporter as a command line app

[cpyrgas]

Add command-line options to VOXporter, so it can also run from the command line without a GUI, so it can be used in scripts.

Added support for the -nogui command line option, in which case VOXporter shows no GUI.

Need to specify source with -s:"c:\folder with aefs or aef/mef/prg file" and output with -o:"C;\Output Folder" or alternatively specify them in VOXporter.ini

One problem is that when run from a console, control returns immediately back to it when running VOXporter, and messages appear afterwards, because VOXporter is still a windows app. Probably only way to fix this is to use a separate Console app that runs the main VOXporter. Will send to customer who requested this (Stavros) and see if it works OK for them for now.
