a few wording tweaks

- Changed some existential constructions (yes, they're really called
existential http://en.wikipedia.org/wiki/Existential_clause). These
aren't innately evil, but rewordings of existential clauses often sound
more direct.
- Changed a "which" to a "that."

     <p>We define light customizations as mostly surface layer changes, things like a color and font changes to existing Bootstrap components. A great example of this is the the <a href="http://translate.twitter.com">Twitter Translation Center</a> (coded by @mdo).

     <p>Instead of using the provided Bootstrap buttons, which only require just one class to start, <code>.btn</code>, we'll add our own modifier class, <code>.btn-ttc</code>. This will give us a slightly custom look with minimal effort.</p>
