candolint: add configuration file

provision: role vars are now legit super evil, confirmed by Ansible 2.1.0.0 They are so extremely high-priority now that they cannot be redefined in a playbook. At least defaults should work as expected?

templates: update Bootstrap to 3.3.7

docs: add candolint badge

docs: redo drone.io badge markup

tests: generate both content-type header and json data in json_payload()

docs: add license (MIT)

provision: `supervisorctl update` already implies a reread

provision: don't pin certs, rely on Mercurial being configured correctly Bitbucket already has a trusted, valid certificate. If extra security is needed, it shouldn't be done in user's .hgrc anyway. And since repo is a variable now, it could be on a host that's not in [hostfingerprints].

provision: if wsgi stuff had any updates, also restart fruitbar
