Allow salt-key -a/-r to work on rejected/accepted keys

This commit modifies salt-key so that -a looks at rejected keys in
addition to pending keys, and -r looks at accepted keys in addition to
pending keys.

The -A and -R arguments still operate on pending keys only.

In addition, this commit improves reporting on the CLI when keys are
rejected and deleted.
Add --include-all arg to salt-key

This commit adds an --include-all option to salt-key, and requires it to
be used in order to match rejected keys with salt-key -a, and accepted
keys with salt-key -r. See
https://github.com/saltstack/salt/pull/7509#issuecomment-25325666 for
more information.

Specify reason for Python 2.7 requirement

While ElementTree is in Python 2.6, we need the expanded support
for xpath which was introduced in Python 2.7.

As discussed in #7264, it might be possible to install
`elementtree-1.3a3-20070912` for Python 2.6, but this is yet untested.
