This adds a *.desktop file to the project, including the NSM keys, for 
tools which wants to find NSM supported applications.

You've to set a icon and maybe add it to your Makefile or similar for 
installation.


X-NSM-Capable sets the value for NSM support (true).

X-NSM-Exec sets the value which should be used as exec value when the 
application is launched in NSM. This can't contain a path or command 
line arguments.
