Use consistent working directory for client

[obydog002]

Fixes #3100

The issue was because the faf client was being opened with the wrong working directory and it could not find the resource files/ binaries it needs to start correctly. This change to the install4j installer file seems to let the faf client consistently have the correct working directory (which is the installation path) no matter how it gets called.

Testing

Linux

• Opening the client from the same and different directories starts the client normally.
• Opening the client from the same and different directories along with a path to a replay file starts the client and launches the replay.

Windows

• Opening a faf replay via right click starts the client and launches the replay.
