Switch yaw and roll selection in settings.

[Nano23456]

This is more of a feature request resulting from missing information.
I had the same problem as the person in this following post where I deliberately changed a setting and it didn't change said setting.
I shouldn't have to read a bug report to find out it will only ever do half of what is says and I have to find the other half in a different menu.
Some ways to fix this without "modifying the player's settings arbitrarily when they change the config", is to simply add some notes about it only changing the mouse controls and/or mentioning that they'll have to continue changing options in controls/keybinds.

Another thing that I just found out and it has some relevance to this and should be similarly easy to fix is that the sensitivity (and probably other values) for yaw and roll don't switch correctly when this setting is applied.
