Merge branch 'master' into hhvm
travis's hhvm version is not recent enough for the tests to succeed.
Whoops.
Added a name to the generator ;)
Merge branch 'master' of github.com:fruux/sabre-vobject
Lets see if travis supports these php versions
Travis doesn't have PHP 5.5.10 (yet), so for now we're just adding it to

I really need a .travis.yml validator so i don't always commit incorrect
configuration.
Is this a spacing thing? lint.travis didn't seem to catch it.
