WYSIWYG should show 'outdent' then 'indent' buttons (rather than reverse) like OpenOffice, LibreOffice, Word, etc

We are current showing the 'indent' then 'outdent' buttons, whereas most editors do the reverse, for example: OpenOffice, LibreOffice, MS Word... Based on a Google images search, even Wordpress's configuration appears to show those buttons in that order, and Panopoly's WYSIWYG was originally based on Wordpress's config.

We should match user expectations!
