BREAKING CHANGES
1: tag.contents() and view.contents(): The parameter order
   has been changed for consistency with other APIs:
     Now:          view.contents(deep, selector)
     Previously:   view.contents(selector, deep)

2: childTags(): now returns element-based tags as well as inline tags

3: Removed support for marking an element-based tag as inline=true

- Added support for tag.refresh for element-based tags too - including
  with non-html targets
- tag.onDispose is now called for both inline tags and element-based tags.
- Added support for data-linking to SVG elements
- Added support for void tags with no self-closing slash (issue #209)
- Added support for two way data-binding on custom tags.
- onBeforeChange support: Now supports returning false in order to
  suppress modification of the target data
- tag.onUpdate support: Now supports returning false in order to
  suppress re-rendering the tag

- Added much improved support for validation
- Added much improved support for custom tags using widgets or plugins
  such as the jQuery UI widgets.
