67	* Check whether a common script is already registered by file name
68	* instead of handle.
69	*
70	* === Used in older versions to check for Cycle script. ===
71	*
72	* Why? Plugins are loaded before themes. Our plugin includes the Cycle
73	* slider. Some themes include it too. We only want to load it once.
74	*
75	* Load jQuery Cycle plugin (http://jquery.malsup.com/cycle/) only if
76	* any version of Cycle is not already registered by a theme or another
77	* plugin. Both versions of Cycle use same function name so we can't load
78	* both but either version will work for our purposes.
79	* http://jquery.malsup.com/cycle2/faq/
80	*
81	* The WordPress function `wp_script_is` checks by handle within a plugin
82	* or theme but handles can be different so it misses it.
83	* wp_script_is( 'jquery-cycle', 'registered' )
84	* http://codex.wordpress.org/Function_Reference/wp_script_is
85	*
86	* Jetpack's slideshow shortcode simply enqueues its own version of Cycle
87	* without registering first if and when the shortcode is rendered. No way
88	* to check for that. It does not seem to create a conflict now. (1.16)
