Wrong parameter name in xfwm4 wiki

https://wiki.xfce.org/howto/xfwm4_theme says:

"Another setting that needs to be set from the “themerc” file is the “title_full_width” parameter. This boolean value determines how the pixmap are arranged in the title bar."

However, looking at the code (as well as actual themerc examples), the parameter is actually called full_width_title.
