Terminal-style syntax highlighting

For documenting on Drupal web sites steps taken on the command line, Agaric would like syntax highlighting of the sort GitHub is using. Note that it is adding a class to the pre tag, and then using spans within that!

Perhaps could be added as a feature to the Code filter module.

<pre class='terminal bootcamp'>
<span class='codeline'>$ git config --global user.name "<em>Firstname Lastname</em>"<span>Sets the name of the user for all git instances on the system</span></span>
<span class='codeline'>$ git config --global user.email "<em>your_email@youremail.com</em>"<span>Sets the email of the user for all git instances on the system</span></span>

</pre>

Geisha module did not install bash highlighting, so Stefan installed Syntax highlighter module.
