[Image2] Breaks with config.contentsLangDirection = 'rtl'

[Marek Lewandowski]

observed at major

It seems that when we'll set text direction to rtl, it will break image2 (at least in our sample).

1. update image2 sample so it will look like that:

   CKEDITOR.replace( 'editor1', {
   	extraPlugins: 'image2',
   	height: 450,
   	contentsLangDirection: 'rtl'
   } );
   

2. open sample with image2 plugin (/samples/plugins/image2/image2.html)

Expected result:
Similar markup/graphic feel as in ltr mode.

Current result:
Code seems to be broken, blocks do overflow to each other etc.

additional info:

1. This is cross-browser issue (at least tested it with IE10, latest FF, chromium).
