ReorderAlgorithm will now handle all the logic associated with the

was copy and pasted into ReorderAlgorithm.java.

I'm moving the LayoutParams to another file to start the decoupling

Also, I change the name from LayoutParams to LauncherLayoutParams to prevent confusion with ViewGroup.LayoutParams making it explicit that this are different LayoutParams.
