Support for tags without closing

Some tags like {% continue %} and {% break %} don't have a closing tag like endif and endfor. Currently, if I add a non-closeable tag in an HTML document, it breaks the syntax highlighting.

For example, while developing a Jekyll theme, if I use a tag like {% feed_meta %}, anything below it will not get highlighted:
