 Proposal RTL support through loading of locale-specific CSS.  Using "fa"
 as an example locale, here's the gist.

  * wp-includes/languages/fa.php contains some locale specific variables.
 $text_direction specifies the text direction, either 'ltr' or 'rtl'.

  * fa.php, if it exists, is loaded into the $wp_locale singleton.  The
 variables defined in fa.php are turned into instance variables of
 $wp_locale.

  * When loading the front page, we check to see if the theme includes
 fa.css.  If so, we load that css after style.css via a 'wp_head' hook.

  * If fa.css does not exist and $wp_locale->text_direction is set to rtl
 and rtl.css is provided by the theme, load rtl.css.

  * For the admin, if the text direction is rtl, load rtl.css from wp-
 admin.  We would ship rtl.css  as part of WP.  It is loaded after wp-
 admin.css.

 Eventually, fa.php could include other locale-specific settings such as
 the strings to use when constructing permalinks.
