Syntax Highlighting for Shell Scripts (Riskable)

Riskable contributed the syntax highliting code for shells scripts, which enables you to display shell scripts (bash/ksh/sh) in a much more readable format.  To use it, switch to HTML mode and insert a <pre> section as follows:

<pre class="script" function="syntax.shell">
# add your script here
</pre>

Thanks Riskable for your contribution!
