Adds scroll mode by the middle button

Version 0.9.6:

• Adds scroll mode activated by the middle button. Useful for trackball mouses without mouse wheel.
• When in scroll mode, the right click deactivates the scrolling for 4 sec., so you can select a contextual menu command, then it automatically reverts to scroll mode. Middle click on a contextual menu immediately reverts to scroll mode.
• Double click of the middle button closes the active tab/window.

System Requirements:

macOS v10.6 (Snow Leopard) - 10.12 (Sierra)
5-button mouse (i.e. Logitech, A4tech, Canyon, etc.), for Copy&Paste with the side buttons 
Any 3-button (or more) mouse i.e. a trackball mouse, for the scroll mode with the middle button

Initial release

System Requirements:

• macOS v10.6 (Snow Leopard) - 10.12 (Sierra)
• 5-button mouse (i.e. Logitech, A4tech, Canyon, etc.)

mouse34Btn maps the copy command to the bottom side button (paste to the top side button). This mapping is tested with a Logitech 5-button mice. However, some mice like Canyon reverse the side buttons, so you may use mouse43Btn app that reverses mapping commands.
