removed alert for IE6
Fixed bug that caused closeEsc:false and closeClick:false to not have any effect.
Separated logic for "close when clicking on the overlay" and "close when clicked on the 'closeSelector' object" so they can work independently
it's now smart enough to detect if a lightbox was already active, and properly handle it (fades out the existing modal while fading in the new one). Disappear effects and properties are now added. the close modal / overlay code was refactored to be more clear, and an extra unbind was added to clean up after myself.
fixed a small bug where I accidentally overwrote the ix to closeClick = false;
delete stray console.log which is breaking in IE
Changed keydown to keypress so that keyCode works in Webkit. Also fixed a logic bug (again! curse the last merge) that keeps the close selector from working if closeClick is set to false.
Lots of changes in this one.

- Cleaned up the way the overlay was being defined. This was causing some event issues in some browsers.
- Now gracefully (if not a little brute forcefully) handles the scenario wherein two modals are created. This typically happens when you call a modal from within another modal.
- Properly handles the showOverlay option
- Handles binding and unbinding events better via the closeLightbox method
- Changed "click" event to a "delegate" handler to handle close events from within ajax'd in modal contents
- Some more CSS trickery to guarantee sweet looking modals in all browsers
- Added appearEase option to allow easing on appear animations
- Simplified appear / disappear speed parameters
- Added showOverlay option
- added parentLightbox option, which will hide a parent and show that parent on close
- Changed default overlayCSS just because

Changed the name of "resize" to "reposition" because that makes a heck of a lot more sense.

checks opts.closeClick before binding click event to overlay
Changed keyup binding to document scope for IE issues

IE7 and 8 were having problems with keyup being bound to $(window). I ha
ve no idea how I missed this until now.
Fixing dirty merge...

When adding a new lightbox, make sure we unbind the keyup from the window (not the document)

This was causing additional unwanted onClose events to be called each time you hit 'escape' (once per lightbox load, which add up eventually)
