Update build.py

[suchyindustries]

As d4lf doesn't update changes "on the fly", I think everybody's behaviour is: after setting up in GUI, start the main program. So this is my proposed change: From now on, after "d4lf.exe --gui" closes, it will automatically start the main d4lf.exe. Try it yourself with this batch script:

@echo off cd /d "%~dp0" d4lf.exe --gui start "" d4lf.exe
