Osu: Change default keyboard layout in osu!standard

[MikelJohnson]

This is proposal to change default mapping to 'A' and 'S'. There are few reason to do this:

1. The default keys in taiko and mania are already on second row in QWERTY keyboards. This would bring consistency to the default keyboard layout.
2. There are few keyboards that have "special" faster WASD keys.

Although this change may be disruptive to current player, it may help newcomers that either have "special" faster WASD keys and cause less confusion in figuring out layout in other gamemodes.

I cannot disagree with this one, for both of the reasons stated.

Another reason would be users with a non-QWERTY keyboard not being forced to change their layout anymore.
E.g. on a german keyboard (QWERTZ) XZ is unplayable as they're very far apart and in different rows.

I suggest SD instead of AS to be the new default though to prevent conflict with french keyboards (AZERTY) while we're at it.

[peppy]

Yes, that's one of the main reasons to do this.

Not sure if anyone actually ever tested this but lazer uses the physical key position. So XZ maps to XY on a german keyboard

[peppy]

That raises a larger issue (it is actually incorrect behavior) and should be fixed as a separate issue.
