Somewhat experimental. If the SYSCONF file is not found or is invalid then generate one. For now ask the user if this should be done. The generated SYSCONF file works for me with the games I have tested, but this needs further testing. Unfortunately, most users will never use this as they will have the SYSCONF file anyway. Eventually we could perhaps remove the distributed SYSCONF, and generate it the first time dolphin is run.
