RTL Fixes, Smarter triangles, and Preselected defaults.
* RTL doesn't flip the order of the banner components, and fit:true containers have widths that are properly calculated.
* Triangles no longer inherit a margin they don't need.
* Variable-ized the spacing in the header for easier consistency.
* Default-selected english as the language.
