Add yui3-skin-sam to example div In most cases, this is unnecessary, but it doesn't hurt. I know because I said that that I'll be rolling back this change because it *did* hurt, but ...you know, we'll see.

Adding event examples. It's not the best suite of examples. One basic DOM subs, two creating synths (one of which is on the gesture synths). The domready and focus examples were cut because domready spent more time in text than example and made incorrect assertions. The focus example because it was using old APIs, CSS, and was practically a small app that mainly illustrated Loader and various other parts of the lib. There's merit in including it, but I'm not sure where, and it will take editing.
