fix for script tags

I found some unexpected behavior:  

    <script>...</script><p>Foo</p> 

will cause the tokenizer to properly emit a "closetag" event for </script> but, all that follows will only emit "ontext" events. 

I assume this behavior exists for style elements as well, but did not check for it.

My fix is to force this._special back to 0 after emitting a closetag event.

I updated the Event/02-template.json test by wrapping the html in a <p>...</p> element to test for this.  Prior to my fix, the </p> would have emitted an 'ontext' event and now it properly emits an 'onclosetag' event.
