Make project board public

[bmpvieira]

The organization wide project board (that gathers all the issues from all the modules) is only visible to members. This makes it hard to show to new potential contributors the state of the project. It's unclear if/when GitHub will allow this to be public. In the meantime we could have a very simple html page that lists the cards by column and is autogenerated using data from GitHub's API:

https://developer.github.com/v3/projects/cards/

This could be simply hosted as a gh-page and built daily using Travis cron jobs. No need to build an Express or React app for on this.
