Add initial appveyor file

[orf]

Refs #120

[orf]

Hmm, this should be starting a build now...

[cfarrow]

I'm looking into it.

[cfarrow]

It ran. I might have the integration wrong at the github end.

[cfarrow]

It looks like notifications are configured in the appveyor.yaml file. https://www.appveyor.com/docs/notifications/#github-pull-request

[cfarrow]

No, I'm misunderstanding something. That build is for master and notifications only need to be configured for custom templates. Still looking...

[orf]

I think that is only for the comment, for example in this appveyor.yml file there are no notifications, but merge requests still get the notification like so: ember-cli/ember-cli#6708

[cfarrow]

I've enabled the webhook. I don't see a way to trigger a branch build from the appveyor interface. Please push another commit.

[orf]

That's the ticket! Awesome, I'll have a fiddle tomorrow and see if we can get at least the installation rather than the building passing.

[cfarrow]

Cool. Thanks for taking the initiative on this!

[orf]

No problem! It seems comtypes uses a VS 2010 build, but the minimum VS that appveyor offers is 2013. Is there any technical reason the project couldn't be updated to 2013?

[cfarrow]

No part of the comtypes library actually needs VS. It's there to build a COM server that is used to test that functionality.

[orf]

Hmm, my test was simply running setup.py install - should it be building the test COM server in that case? I've changed it to a pip install so lets see if that helps.

[orf]

Oh, my bad, it appears that AppVeyor triggers the build automatically.

Hey @cfarrow - this MR is ready for merging if you're happy (you might want to let github squash it when you do).

I tried to get the tests to run as well but failed. I think they are somewhat broken and need a lot of work to get them running, but for now just running setup.py install on the various python versions is a win.

So as I see it the tests appear to run on Python 2.7 32bit only only. 2.6 runs, but fails due to a missing testcase method (https://ci.appveyor.com/project/cfarrow/comtypes/build/1.0.9/job/6uxqxeleqe7j0hgi). All 3.x cases fail with an AttributeError (https://ci.appveyor.com/project/cfarrow/comtypes/build/1.0.9/job/i528o3q1kwvqdt1v).

It seems the tests in general are in a poor state, with a custom test loader that seems pretty old. I'd quite like to convert them to pytest if you're willing?

[cfarrow]

We can merge this as-is. I may record the test failures as their own issues, depending on how long they persist. I've moved the pytest discussion to #123.

[cfarrow]

Thanks for setting this up!
