Add line ending conversion (yes I'm on a PC)
Adding two things:
* Stub of 'phpunit' tests & test bootstrap
* initial Travis CI config

(Note: Still in testing, having trouble with submodule locally)
Travis tested-branches config changed

Switched to whitelist, only local 'travis-ci' branch in-use now
Travis will only test master branch, for merge to origin

[ci skip]
...and that will skip Travis build of this commit
