robotframework

Sorry it took me so long!

As @datakurre mentioned, a couple of steps are required after merging this pull request, because right now the secure values in env.global of .travis.yml are tied to my SauceLabs account.

http://developer.plone.org/reference_manuals/external/plone.app.robotframework/happy.html#integrate-to-sauce-labs

So, first you need to decide which email address is going to be associated to the SauceLabs account, then an account name.  Due to limitations with the free (open sauce) account, I think each Github product needs its own account.

Let me know if I can help with any of this.
