Support Vars Inside UL Vars

[jeresig]

Right now you can't use <var>s inside of <ul>s. For example:

<ul id="STATEMENT">
  <li><var>V1</var> is directly proportional to <var>V2</var></li>
  <li><var>V1</var> and <var>V2</var> vary directly</li>
  <li><var>V1</var> varies directly with <var>V2</var></li>
  <li><var>V1</var> and <var>V2</var> are in direct variation</li>
</ul>
