Integrate travis-sphinx tool and remove doc_upload.py

[Syntaf]

I finished a lightweight tool that can be installed and called via pip, so I went ahead and changed this implementation which cleaned up a couple things. I also removed the encrypted token as you can actually specify this manually on travis-ci's page. This is found in the settings tab

This is really neat. I'll be testing everything out and updating the documentation pages. I'll let you know if it slugs and compile some of the instructions you've put together in one place on the developers pages.

thanks, it's currently running on travis-ci's legacy infrastructure which means it can take a couple minutes to finish a build. legacy supports the use of sudo which is currently used in the script

It would be better to upgrade to their current infrastructure(which guarantee's a build within 10 seconds of pushing a commit) however I cannot find a workaround for the use of sudo on line 9 and 10 in .travis.yml. Maybe i'll find a fix in the future

Great, i checked the logs and saw the warning but figured you'd already noticed. It's a nice to-do item. I've created an issue at #58

feel free to edit for correctness.
