greeter unlock configuration

In addition... Until we split out the greeter into a proper LightDM greeter, we have a goofy, insecure, demo method of setting password/pin:

Edit/Create the file ~/.unity8-greeter-demo with the following syntax:

[General]
passwordValue=4890
password=pin

Where password can be "none", "pin", or "keyboard". And passwordValue is either the PIN value or passphrase, depending on the type of password.

Obviously, this is just a temporary solution, but it should be easy to implement in the meantime and will get the UI to work until we have a proper split.

Oh and should have mentioned... the "password" key is working today but uses hardcoded values of "1234" or "password" depending on type.

The "passwordValue" key support will be added by https://code.launchpad.net/~mterry/unity8/custom-password/+merge/183935

Note that passwordValue support now exists in unity8 trunk.

---------------
ubuntu-system-settings (0.1+13.10.20130910.3-0ubuntu1) saucy; urgency=low

  [ Sebastien Bacher ]
  * background: use the new OptionSelector, tweak the UI to be closer
    from the visuals (move the labels at the bottom of the images, use
    smaller text, use correct spacing).
  * battery: set current value on the graph.
  * reset: implement backend to reset the unity launcher settings.
  * storage: display the clicks' list rather than the fake datas.
  * updates: use the new ItemSelector widget, updated the download
    option to match the current design as well, moving the selector in
    its own subpage.
  * orientation: replace "Rotation lock" by "Orientation lock".
  * language: use new ItemSelector widget.
  * storage: use new ItemSelector widget.
  * battery: on the desktop use idle-delay's key, which is not
    deprecated.

  [ Iain Lane ]
  * Make the panels display "Lock on idle" or "Sleep on idle" as
    appropriate.
  * Add UI and backend for setting the time manually.
  * Make the "Change passphrase" / "Change passcode" button work.
  * Implement filtering in the main window.

    (LP: #1218010)
  * security-privacy: Implement changing password and validation of

  [ Charles Kerr ]
  * Fix NMClient leak, take battery capacity into account when
    determining the last time a discharging battery was full.

  [ Ken VanDine ]
  * Don't start the transfer from the importer, the hub now handles that
    when dispatching the transfer.

  [ William Hua ]
  * Replace page stack with sheet in display languages. (LP: #1222728)

  [ Adolfo Jayme Barrientos ]
