Skipping non-standard layerX and layerY. Reference to the original event...

[paulredmond]

Chrome is ditching non-standard layerX and layerY properties and generates tons of console warnings:

"event.layerX and event.layerY are broken and deprecated in WebKit. They will be removed from the engine in the near future." Affects Chrome 16x

Issue documented here: http://code.google.com/p/chromium/issues/detail?id=101733

jQuery 1.7 removed these in 1.7 as well, reference (see Removed Features): http://blog.jquery.com/2011/11/03/jquery-1-7-released/

I also added reference to the original event so other browsers can still have access, but I can remove that from the PR if you'd like.

See also #46 and #39
I like that you've split up the properties but I don't think the .split() is a great idea on each call, best if that's done once at init.

I did not test this enough, sorry for jumping the gun.

I might pull your conditional property copies info #39, I wanted to do that myself but couldn't be bothered sorting out which event types need which properties.
I also like referencing the source event but perhaps @fat may have a different opinion on that.

@rvagg cool, I agree that I should not have called split in the function, bad idea :) I didn't realize your PR addressed similar to mine, thanks for referencing your PR.
