RTL support

I try to translate my project to hebrew
but the text direction is always LTR
this make a problem

here is an example: jsfiddle
pay attention - this is not the text align, this is the direction of the text itself

here is a good explanation: https://www.w3.org/International/questions/qa-html-dir

the simple solution is to add dir="auto" to each textarea on the editor
