This program tests the startup time of the given application with and
without launcher.

Requirements:
1. DISPLAY environment variable must be set correctly.
2. DBus session bus must be running.
3. DBus session bus address must be stored in /tmp/session_bus_address.user.
4. Given application supports launcher with .launcher binary in /usr/bin/.
5. launcher application should be installed.

Usage:    test-func-launcher <launcherable application>

Example:  test-func-launcher /usr/bin/fala_ft_hello
