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.
The launched application inherits the environment of the launching
process, but it can be modified with g_app_launch_context_setenv()
and g_app_launch_context_unsetenv().
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.
