commit a625c19ef0f65ed3a690d298e24dc5c999fb6487
Author: Thomas Sibley <trs at bestpractical.com>

    Permit <bdo> tags and the lang and dir attributes when displaying HTML
    
    The <bdo> element and lang/dir attributes are used in mixed language
    contexts and they are often essential for correct display.  CKEditor
    will also generate the attributes if properly configured, so RT
    shouldn't scrub them out.
    
    Refer to http://www.w3.org/TR/html4/struct/dirlang.html#h-8.1 for the
    source of the acceptable values.
    
    Resolves [rt3 #19691].
