A bunch of existing code assumes that <tab> elements are the immediate
and only children of a <tabs> element, and uses dom apis to traverse
relationships between these elements. To simplify conversion of <tabs>
to a custom element (and hopefully improve readability a bit at the same
time!), introduce new apis:
On <tab>
this.parentNode -> this.container
this.nextElementSibling -> this.container.findNextTab(...)
this.previousElementSibiling -> this.container.findNextTab(...)
On <tabs>
this.children -> this.allTabs
