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