Change the naming of the Mouse buttons for keybinds

In the keybinding section the mouse binds are 'incorrectly' named for the mouse buttons. Mouse 1 (Left click) isn't bindable, fair enough, but when doing Mouse 2 (Right click) it will refer to it as "Mouse 1" within the keybind menu. All mouse buttons are 1 off, Middle mouse is marked as "Mouse 2", Back is marked as "Mouse 3" and front is marked as "Mouse 4".

I propose these be changed to their more commonly used names of "Mouse 2" being right click, "Mouse 3" being middle click / scroll click, "Mouse 4" being back button, "Mouse 5" being forward button.
