Adding RTL support to Cell Widgets. CellBrowser opens from the right in RTL mode.  CellTree open/close icons appear on the right in RTL mode.  IconCell shows the image on the right.  As part of this change, I had to change the location of the ruler in LayoutImpl.  It used to be shifted to the top and left out of view, but this causes unintended scrollbars in RTL mode.  Shifting it off to the top does not affect scrollbars, but still hides the ruler completely.

We will add bidi support to cells in a seperate pass, which will set the direction of text based on the content being rendered.
