r97623: some fixes for RTL in IE70Fixes.css:
* Remove useless .rtl #bodyContent a.external rule, already handled by CSSJanus
* Flip the div#column-content div#content hack in RTL mode so the content area doesn't end prematurely on the left
* Fix display of the user icon next to the login link or user name
* External link icons are still broken in IE7+RTL, but they were already broken in 1.17 and are also broken in Vector
