Launches the application. Passes files to the launched application
as arguments, using the optional launch_context to get information
about the details of the launcher (like what screen it is on).
On error, error will be set accordingly.
To launch the application without arguments pass a NULL files list.
Note that even if the launch is successful the application launched
can fail to start if it runs into problems during startup. There is
no way to detect this.
Some URIs can be changed when passed through a GFile (for instance
unsupported uris with strange formats like mailto:), so if you have
a textual uri you want to pass in as argument, consider using
g_app_info_launch_uris() instead.
On UNIX, this function sets the GIO_LAUNCHED_DESKTOP_FILE
environment variable with the path of the launched desktop file and
GIO_LAUNCHED_DESKTOP_FILE_PID to the process
id of the launched process. This can be used to ignore
GIO_LAUNCHED_DESKTOP_FILE, should it be inherited
by further processes. The DISPLAY and
DESKTOP_STARTUP_ID environment variables are also
set, based on information provided in launch_context.
