better autoscroll от Coded-Eye

Simple to use and way more convenient than using the extension bar to change the speed.

Usage :
Crtl + left mouse click somewhere in the page to enable.
The proximity of your cursor to the origin of the click (shown by an image) will change speed.
Works both in the X and Y axis.
Click on the page to disable the auto scrolling ( Will ignore links while auto-scrolling is enabled ).
