docs(ngHref): close the <a> tags in examples

Self closing <a> tags in the examples given make no sense because they won't
show up in the browser (and I think aren't even allowed according to HTML specs).
I've seen this confuse people over at stackoverflow.com who tried to copy/paste
those examples.

fix(jqLite): allow `triggerHandler()` to accept custom event

In some scenarios you want to be able to specify properties on the event
that is passed to the event handler. JQuery does this by overloading the
first parameter (`eventName`). If it is an object with a `type` property
then we assume that it must be a custom event.

In this case the custom event must provide the `type` property which is
the name of the event to be triggered.  `triggerHandler` will continue to
provide dummy default functions for `preventDefault()`, `isDefaultPrevented()`
and `stopPropagation()` but you may override these with your own versions
in your custom object if you wish.

In addition the commit provides some performance and memory usage
improvements by only creating objects and doing work that is necessary.

This commit also renames the parameters inline with jQuery.
