Rewrite the signature management UI from top to bottom.

  - Break the UI out of Glade and into small, manageable widgets:

      ESignatureEditor     (moved from mail to widgets/misc)
      ESignatureManager
      ESignatureTreeView
      ESignatureScriptDialog

  - Move several signature utilities to e-util/e-signature-utils.c so
    they're accessible from widgets/misc without introducing circular
    dependences.

  - Have EMailShellModule listen for new GtkhtmlEditor windows (from which
    EMsgComposer and ESignatureEditor are derived) and configure the window
    with spelling and HTML editing user preferences.

  - Drastically simplifies em-composer-prefs.c.
