LavaLamp - a jQuery animated menu plugin

LavaLamp is a plugin based on Guillermo Rauch and Ganesh Marwaha's previous plugins for mootools and jQuery 1.1.x respectively. Using the Sliding Doors CSS / Javascript technique, LavaLamp allows you to add nifty background hover effects to HTML lists in combination with the Easing library.

New in 1.3.3 requires jQuery 1.3.2

fixed: added closure with null passed argument for move() command in returnDelay to fix errors some were seeing - thanks to Michel and Richard for noticing this.
fixed: changed mouseover/out events to mouseenter/leave to fix jerky/stuttering animation problem when using large margins on LI elements. Thanks to Thomas for the solution and Chris for clearly demonstrating the problem.
enhanced: New! Multi-layered Menu support - added 'noLava' class detection to prevent LavaLamp effect on LI elements with this class. See the demo page for details (at the bottom.) This fix bumps the requirement to jQuery 1.3.2
enhanced: modified to better automatically find default location for relative links. Thanks to Harold for testing and finding this bug.

patched to remove stray $ references inside plugin to work correctly with jQuery.noConflict() mode.

autoReturn: true - if set to false, hover will not return to last selected item upon list mouseout.
returnDelay: 0 - if set, will delay auto-return feature specified # of milliseconds.
setOnClick: true - if set to false, hover will return to default element regardless of click event.
homeLeft: 0, homeTop: 0 - if either set to non zero value, absolute positioned li element with class .home is prepended to list for homing feature.
homeWidth: 0, homeHeight: 0 - if set, are used for creation of li.home element.
returnHome: false - if set along with homeLeft or homeTop, lavalamp hover will always return to li.home after click.

two big changes were made to the internals that may affect upgrading to this version. make sure to update your CSS class names and change linum to startItem when you upgrade!
a bug in the first few versions with the linum parameter created a nifty out-of-bounds fly in effect that several people requested as a feature, so the home features are born!
known issue: IE may throw an error if using an out-of-bounds home with too small height and width - this is being investigated here: http://dev.jquery.com/ticket/3881

New default routine automagically attempts to match the location bar info to the appropriate link href tag for the active page - this should prevent need to use linum/startItem in most situations
click method now returns true by default, allowing link follow
cleaned up the original code for readability and efficiency

Many thanks to everyone who came before me on this project!
