Add July 2014 VM update announcement

The Android update shall be coordinated with the [documentation update](https://github.com/travis-ci/docs-travis-ci-com/pull/91).
I will probably have some time tomorrow to give a look to these updates, I'll merge the PR once the versions available and the provisioning ok.


Thanks Graham!
