Start Game Develop shellscript doesn't always work (Linux)

Especially when executed from other dir or by WM that doesn’t respect working directory like IceWM. Proposed solution is to add following line at the very beginning of script, just after #!/bin/bash:

cd "${0%*/*}"

That will fix issue so it will work good even when executed from other directory than one that have this script in it.

I’ve added it to the script, thanks. :slight_smile:
