How to specify custom builder?

[Dubrzr]

Hi,

I see at https://github.com/Syntaf/travis-sphinx/blob/master/travis_sphinx/build.py#L36 that it is not possible to specify a custom builder?
Can you fix this, please?

Thank you!

Sorry for the late reply Dubrzr. I'm quite a bit busy in life at the moment, but I'd be happy to merge in a PR that allowed a custom builder for this repo.
