import from django.conf instead

you should always import from django.conf rather than importing
from the local package. That way, things like the
@override_settings decorator in Django 1.4 will work.
docs(standards): add commit style guide

this introduces a new commit standard for Deis developers. The
goal of this commit is to allow developers to search through
the history better, provide us better information through
commit messages, and eventually allowing us to script the
CHANGELOG.md so that we do not have to rely on a third-party
tool to do the parsing for us.

to be updated to reflect the new workflow changes.
docs(standards): use proper english

couple of breaking changes, including the change to rename
all_ssh_keys() to ssh_keys().
