Create .travis.yml

Check to see if branch local .travis.yml works.

I enabled it on travis, I think.

[techtonik]

@matthew-brett I believe it needs a commit to bootstrap - https://travis-ci.org/mingwpy/ - merging this one should be fine for a start.

[matthew-brett]

Isn't this windows specific?

[techtonik]

Yes. Sorry, I am on Windows so I forgot that it is for Travis and not for AppVeyor.

[matthew-brett]

Suggest adding

python:
    - 2.7

before_install:
    - pip install sphinx

[matthew-brett]

Oops, then:

    - pip install linkchecker
script:
    - make html
    - linkchecker _build/html/index.html

[techtonik]

Squashed some commits for clarity.

[matthew-brett]

I think you still need:

install:
    - pip install -r requirements.txt

[techtonik]

No. Click the green commit checkmark or expand "All checks passed" box to see for yourself. =)

[matthew-brett]

I stand corrected ...
