A fix for Chunky 1.4.0 launching problems

Chunky 1.4.0 was not working for some people. When trying to launch Chunky nothing happened. Thanks to some bug reports from users it was easy to identify the issue which was caused by a bug in the Chunky Launcher.

If the Chunky settings directory was not configured before the launcher tried to start it would crash. The first-time setup dialog should have been shown to choose the settings directory, but the rest of the launcher tried to initialize itself before that happened leading to the crash.

I have updated the installer for Chunky 1.4.0 so the launcher should hopefully be working once again when making a fresh install.
