Allow natural scrolling for mouse (not only touchpad)

[bittner]

 * Cinnamon version: 3.2.7
 * Distribution: Ubuntu 17.04 Zesty
 * Graphics hardware *and* driver used -- n/a
 * 64 bit

Issue

The System Settings > Mouse and Touchpad dialog should also handle natural scrolling for for mice, not only for touchpoads. When I use a mouse I should be able to use the scroll-wheel as with natural scrolling.

This is somewhat a follow-up on issue #1930 and PR #1940.

Steps to reproduce

• On a Cinnamon desktop go to the System Settings (via the Menu / System Settings))
• In the System Settings go to "Mouse and Touchpad"
• Look for a "natural scrolling" or "Reverse scrolling direction" in the "Mouse" tab -- it's not found
• Look for a "natural scrolling" or "Reverse scrolling direction" in the "Touchpad" tab -- it's there and affects only Touchpads, of course

Expected behaviour

The System Settings > Mouse and Touchpad should have a general "Reverse scrolling direction", or also (a separate) one in the Mouse section.

This would have to be implemented to cinnamon-settings-daemon.

Thanks! See linuxmint/cinnamon-settings-daemon#192

Why was this closed? This is an important feature that I see no reason to not have. I would love to have "natural scrolling" for the mouse, that's the main reason I'm not currently using Cinnamon. Same for Mate. If this simple feature could be added it would be greatly appreciated. Thanks in advance.
