Replays folder should not be a requirement to a valid osu! directory about rewind

[abstrakt8]

The reason why I want the "Replays" folder to exist is that file watching can not work on folders that do not exist (using chokidar). This means if the user exports a replay for their first time, then Rewind won't be able to detect that new file unless Rewind gets restarted (then it also starts watching on an existing "Replays" folder)

I don't want to create an empty "Replays" folder in the osu! directory because, generally speaking, the only way I want to access the game related files is through reading in order to avoid creating any game breaking issues.

Thanks,
I will look into rewriting/relaxing the setup process:

• Reading from osu!.[username].cfg to determine the correct "Songs" folder
• Dropping the requirement of the "Replays" folder
