Run codeception checks on a local PHP dev server in travis
Another go at codeception runs in travis

We need to do a PHP version check to see whether the PHP dev server
is available. If PHP version is below 5.4.0, we'll skip the functional
tests.
Fixed error in travis config
Fixed PHP version detection for travis/codeception
Fixed version reporting in codeception wrapper script

run-function-tests should now exit cleanly if PHP version is below 5.4
Restructured acceptance tests
More test users and tests for acceptance

to "solve" the issue.

For the curious, here's the source code for htmLawed():
