No option for mouse controls

[yeemvrother]

In the controls menu, there is no way to alter mouse button input. I always play with right and left mouse swapped, and not having that option prevents me from enjoying this mod as much as I would like to. Would it be feasible to add that into the controls?

As a second note, when I install optifine, I usually set zoom to middle mouse click, but zoom was unable to be set to middle click... This is less of an issue than the swapping of mouse buttons, but as it relates to mouse controls I'll add that here as well.
