Add spacing between items as decorations instead of margins

There are bugs in the accounting for the margins if we manipulate the
view directly, causing the wrong top to be reported and the view to be
shifted when we call scrollToPosition. Item decorations ensure that the
layout system for the recycler view always has the right details about
the spacing.
