- Correct bug when running git update-requirements when there are more than 2 requirements files in the repo.

- Add more Ansible configuration options via environment varible because ~/.ansible.cfg is not read if there's an ansible.cfg present in the current directory.

- Fix bug with SSH config generation, order was not correct (keep safe handling of unusual filenames).

fixup! - Removed install script, found a much simpler way to install. Updated README accordingly. - Reverted OSX TravisCi test since the only test is using pre-commit now.

- Added Documents/bin directory for scripts, moved renew-certs,
train-wifi and dma-clean (wasn't commited before) there.
- Made gen-ssh-config a script (in Documents/bin) instead of a shell
alias. Call said script in the post-merge git hook (instead of sourcing
bashrc which currently just exits if not running interactively which I
like to keep doing). Added said scripts to pre-commit.

git hook).
- Fix issue with failure to source bashrc in the post-merge git hook
(file not found issue).
