Automate CF.com documentation updates
After we document how to update CF's documentation, let's automate the process. Hopefully this would be as simple as having Travis checkout gh-pages, run gulp and pushing to GitHub.
See https://github.com/cfpb/capital-framework/pull/328#issuecomment-230516433.
WIP PR https://github.com/cfpb/capital-framework/pull/504
https://github.com/cfpb/capital-framework/pull/908 will pull the docs direct from the code in master.
#908 is merged! Good riddance, gh-pages branch.
I think one last step to closing this out (as discussed in chat with @anselmbradford) would be to create a check in Travis that runs gulp docs on a PR and fails it if it dirties any files in the tree.
