Fix SVG insertBefore/insertAfter when wrapped in <a> when setting "href"

When an element has an "href" the node is wrapped with an <a>.
insertBefore/insertAfter did not take this into account (#631).
Additionally, remove, toFront and toBack now use the new function.

Change the version in bower.json to match the tag name.
