Title: Autoscroll when dragging

Autoscrolls the container element while dragging if you drag the element over the offsets defined in scrollTriggers config option.

Also you can enable/disable this behaviour (disabled by default to be backwards compatible) and control the scroll sensitivity and speed.

New available options are:
```
* scroll (false) Enable or disable the scrolling behaviour
* scrollSensitivity (1) Mouse movement needed to trigger the scroll
* scrollSpeed (5) Speed of the scroll
* scrollTriggers (obj) Distance from the border where scrolling become active
top: 40
left: 40
right: -40
bottom: -40
```
