NEW Amend Travis build to run a simple PHP_CodeSniffer test.

At this stage, the test just checks line-length and line-endings, but previous commits have ensured that framework actually passes those tests.  We can add more tests as we actually correct the code to pass those tests, and grow the test suite, as we had for unit tests.
