Unreasonable values for 'expire' (after 9999-12-31
on Linux, before 1975-01-01 on *BSD) get divided
by 86400 (number of seconds in a day) when too big
or multiplied by 86400 when too small.

Tested on CentOS 6 (Salt 2015.5.5) and FreeBSD 10.2
(Salt 2015.8.0) with following values:

  - 24854 (2038-01-18 in days since epoch)
  - 157766400 (1975-01-01 00:00:00 UTC in seconds since epoch)
  - 3313526400 (2075-01-01 00:00:00 UTC in seconds since epoch)
  - 16000 (2013-10-22 in days since epoch)
  - 18000 (2019-04-14 in days since epoch)

This version complains that "argument port can not be used in
conjunction with argument hash_hostname", so add hash_hostname
to the fields we handle in the formula so we can override it
if needed.

sry, could not resist.

This formula doesn't really require the sudo group (unless
there are actually users in that group). Moreover, on FreeBSD
the 'admin' group would be wheel and not sudo.

This reverts commit a0392693e3.

Fixes #82.

This will allow users change their passwords after the initial setting in Salt.

SSH key pairs deployed via the user's ssh_keys_pillar dict aren't
handled the same as the user's ssh_keys, e.g., file ownership and
permissions aren't specified, and the keying material gets copied
directly into the SLS file.  This change rewrites the two templated
file.managed states to behave as follows:

  - set the files' owner to be the user

  - set the files' group to be the user's primary group

  - for the public key, set the mode to 644 (u=rw,go=r)

  - for the private key, set the mode to 600 (u=rw,g=)

  - pull the files' contents directly from pillar

This adds the ability to manage the ~/.ssh/config file for users.

This has been causing issues for many people, as the remove_groups options is undocumented.  In the 2014.7 release this is changing, and remove_groups will default to false:
https://github.com/saltstack/salt/issues/13276

I'm going with false by default, as it's our use case and it will soon be the default.  If people believe this module should default to true and remove groups not listed, I think that's open for discussion, but we should at least add the option.

This also made it necessary to introduce an additional entry 'shell' into the
users lookup table as the formula previously conflated the shell used for
running the visudo command and the default shell to be used for user accounts.
