Title: Update files/usr/lib/cinnamon-settings/cinnamon-settings.py

Added the mouse button modifier entry, so Blender users can easily change that setting since it's vital to properly use Blender without having to reconfigure it (workflow). "Alt+Right Click" interferes with the Blender shortcut for "Edge Loop Select". On top "Alt+Right Click" opens the same menu as "Alt+Space" so in my opinion it's quite superfluos. Should you prefer to keep it, I'd suggest to map the mouse button modifier to instead by default.
