[gnome-online-accounts/wip/pocket: 2/4] Add Pocket support

commit 6aedcc5bffa57b0b19a4b029985410390e3f1aeb
Author: Bastien Nocera <hadess hadess net>
Date:   Fri Jul 19 17:08:20 2013 +0200

    Add Pocket support
    
    Based on the documentation at:
    http://getpocket.com/developer/docs/authentication
    
    Icons by Jakub Steiner originally from:
    https://raw.github.com/gnome-design-team/gnome-icons/master/web-accounts/tango/src/web-accounts.svg
    
    v2:
    - Make it work
    
    v3:
    - Fix the memory leaks
    - We didn't make apps crash by adding an account type,
      goa-daemon -r did:
    See https://bugzilla.gnome.org/show_bug.cgi?id=698726
    - Implement is_identity_node()
    - Partially implement is_deny_node(), see below
    
    v4:
    - Detect the Cancel button, but that only seems to work once
    
    v5:
    - Disable by default
    - Print enablement status at the end of configure
    - Show client ID as well
    - Fix crash when cookies were set
    
    v6:
    - Add icons by jimmac
    
    v7:
    - Chain up in finalize
    - Set error when processing the redirect URL
    - Update POTFILES.in
    
    TODO:
    - Sync network calls in build_authorization_uri() and
      process_redirect_url()
    - Cancel button doesn't work when we click "Sign Up" first
    
    Doc problems:
    - is_identity_node() shouldn't say it denies access...
