Scroll element into view with different strategies

[DavidGangel]

Implement a way to tell selenium how the scroll element into the view should behave.
It could be told by capability or any other way, it's up to you.
The most important part is that it should work across all the supported browsers.

Example:
ScrollElementIntoView.Top
ScrollElementIntoView.Center
ScrollElementIntoView.Bottom

This would be nice to tell selenium once when it starts the browser and be able to change if needed during the test run. This is for flexibility.
If no value is provided use Top as it is at the moment.
