Bootcamp: Further improvement

Following the suggestions by @vitorfs and questions by @dwayne on #57 I wanted to set a list of potential improvements:

• [x] Migrate to Python 3.
• [x] Keep backwards compatibility with Python 2.
• [x] Add coverage (suggested on my most recent PR #65 as suggested in #48).
• [x] Add coveralls badge.
• [x] Add requirements monitoring (requires.io is the one I have in mind).
• [x] Add requires.io badge (that's because that's the service I know of)
• [x] Run isort on the project (well, this can be done by hand to, and I have cleaned a little bit already).
• [x] Run Flake8 on the project.
• [x] Polish the code structure applying a more 12-Factor style (as suggested in #55).
• [x] Add docker to the development flow (as suggested in #51).
• [x] Implement CBV (I actually have doubts about this one suggested in #50 but I guess than at least it should be discussed).
• [x] Implement better user management and it's workflow functionalities (password recovery, social networks integrations, account creation, login management, correct redirect) as suggested in #86, #53, #32, #28 and #2.
• [x] Add tests to the apps to validate functionality and that way incrementing test coverage, as suggested in #63 and complemented with the requirements from #48 and #65 which were already solved.
• [x] Add better tagging management. As suggested in #54, #73 and #74.
• [x] Implement a nice release cycle on the project (I have to work on this because I'm not that really aware of how it works)
• [ ] Add Tox to the project.

On the next list I would define some additional requests, perhaps too old and somehow relegated to the _nice to have_ drawer:

• [x] Improve keyboard shortcut to submit comments, perhaps accepting _CMD + Enter_ on OS X, just like GitHub (As suggested in #29).
• [ ] Add User reputation system and its respective management process so it can be overrided (as defined on #19).
• [x] Implement better internationalization (a really wild idea, but who knows).
• [x] Display the list of users who liked a given feed, on hover (As requested on #21).
• [ ] Federate multiple instances of bootcamp (As suggested in #31).

Do you both have additional suggestions, requests or goals? As an example, badges are really nice, but there is no need to have all of them, do you have some ideas about which badges the project should have?

PD 4-12-16: Updating the list to include requirements monitoring and the proper badge.
PD 18-12-16: Updating the list to include the reputation system.
PD 13-05-17: Updating the list to include the requirement to add testing to apps.
PD 3-7-17: Updating the issue to add a list of _nice to have_ and forgotten requests.
