Tobias Platen's patch to allow passing subsequent files to Audacity on Linux

Tested on Win and Mac that patch builds and does not affect current
functionality.

Tested on Ubuntu 13.10 dragging audio files to Audacity icon, using file
manager Open (with association set to the format), file manager Open with, and
importing files at command-line using "audacity file1.wav file2.wav".

Works well in preventing "Audacity is already running". Big improvement.

Multiple files are still a problem. With the patch, multiple files can be now
be imported with all the above methods if Audacity is not running. But if
Audacity is already running, only one of the multiple files will import (no
error appears). This isn't a Linux limitation as e.g. Gedit and LibreOffice
open multiple files when already running. Also Audacity on Windows and Mac does
not have this limitation.
