* added clickThrough option to allow click to go to page, even if href and tipAttribute are equal.
* added experimental mouse tracking option
* added simple/experimental delayedClose option to allow auto-closing of clueTip after given number of milliseconds.
* added "focus" as an available value for "activation" option. Will show clueTip on focus of a form element, hide on blur.
* added support for bgiframe plugin. When the bgiframe plugin is referenced in the docuement, clueTip will use it (in IE6).
* cleaned up default ajaxProcess option.
* provided public access to all default plugin settings (thanks malsup!)
* fixed bug (reported at http://jquery.com/plugins/node/941) when splitTitle is used and title attribute is empty
* fixed bug where a variable was improperly nested in an if statement
* fixed bug with incorrectly disabling link when no href is present in invoking element
* fixed annoyance (reported at http://plugins.jquery.com/node/1081): default title attributes showing before cluetip when using long interval in hoverIntent.
* fixed bug where hoverIntent's timeout setting wasn't working with mouseoutClose when user moused out of the clueTip
* fixed problem with setting width option to "auto". Now, non-number widths such as 'auto' default to 275px.
* fixed bug with activation by click where it wouldn't show clueTip under certain circumstances
