 user-agent checking is removing visual editor in function
 user_can_richedit. It took us many days to find a problem, which is
 described here: http://www.benjaminhorn.se/code/wordpress-visual-editor-
 not-visible-because-of-user-agent-sniffing/

 It is not sensible to use user-agent as a check whether to show visual
 editor. Hopefully this check can be amended or removed in future WP
 versions.

 There are various hosting environments where this check fails. Plus you
 would constantly need to manually add new strings over time.

 We need to write plugins or theme hacks to circumvent this problem (that
 is after spending days of struggling to pinpoint the problem).
