Breaking changes:

• Removed Element.text and Element.children, using Element.content instead.
• content items that are not List, Component, String, Node or BuildFn will be converted to String (and to Text).

Updates:

• Fix: BuildContext.ancestors did not include Components.
• Fix: classes were not updated when the new Element had no class.
• Fix: attributes were not updated when the new Element had no attributes.
• Fix: reduce the non-keyed reuse of DOM Elements that have non-matching style properties. (using key reuses them)

• Fix: root component was not added to ancestor list.
• Enable multiple (and non-component) children as root for a View.
• New node helper (br).

• Initial version.
