Add options for custom selectors.

[jasonfarrell]

This allows users to pass a selector for the tab content and any selector for tab links.
It keeps the defaults.

I'm fixing the new conflicts now…

@vdw ready to be merged — if you agree with my changes!

👍

Could really use targets classes so the tab list can be outside the scope of the tab contents.

somewhere else on the page

<div class="tab-list">
  <a href="overview">Overview</a>
  <a href="directions">Directions</a>
</div>

main content

<div class="tabs">
  <div class="tab" id="overview">Tab 1 Content</div>
  <div class="tab" id="directions">Tab 2 Content</div>
</div>

@jasonfarrell @vdw Any luck fixing those merge conflicts?
