 require_if_theme_supports() was a nice idea at the time, but we've never
 found reason to leverage it. Let's remove it, and always include post-
 thumbnail-template.php.

 As it is, some of these functions are useful when post thumbnails are not
 supported by the theme. (get_post_thumbnail_id(), for example). The whole
 file with these functions is under 100 lines.

 Always including this file has the benefit of avoiding a sysopen call.
 opcode caching FTW. see #17112.

 No plugins use require_if_theme_supports().
