Title: Enable memcached service on travis for running cache tests.

Enable memcached service on travis for running cache tests.

Not sure, if its intentional not to run the service.

Also http://about.travis-ci.org/blog/2013-11-18-upcoming-build-environment-updates/ states the service is not
started automatically on boot as before.
