Useful!

Two things:

1. Any chance you could add a brief bit of documentation about these to the Adapt API Wiki page?
2. I can totally see why you did it - but it does seem a little odd to have some code that addresses a totally separate issue (RTL layout issues #2389) in here. It also doesn't completely fix the issue (in that although the DOM order is now correct the layout - in medium/large screen size - isn't. Using block b-05 as an example, when in RTL mode, the text component c-05 should be on the right and the graphic component on the left). I wonder if it would be better to do this as a separate PR that includes the layout fix? Not sure whether this is best done by re-assigning the .component-left and .component-right classes or by amending those classes for RTL mode. Suggestions welcome...!
