Isolated module tests

Alternate implementation for #16, but using TravisCI own isolated test environments.
Built on top of #29 - review commits from 3eb32a2 	"Allow envs testing specific modules" onward.
Not playground but tests: it tests if features are correctly implemented. So we need to add a rather "neutral" dependency repo to be able to test. This one looked like the best candidate to me.
