Title: Graceful fallback to plaintext code when Pygments is missing

**The Problem**
As a Docco user, I want to be able to produce non-highlighted documentation when Pygments is not available, rather than failing to produce any output whatsoever, and exiting the process with a failure code.

**The Solution**
When the Pygments output is not present, output escaped codeText for each section.

**Testing**
There are no direct unit tests for this functionality, but it is directly tested by my continuous integration build, on my [fork of Docco](https://github.com/justindujardin/docco), which does not have pygments available during the build tests.

This pull request has the side-effect of enabling, but does not include support for, continuous integration testing of Docco via travis-ci.
