[geary/bug/728002-webkit2: 63/140] Re-enable spell checking in composer.



commit f69c461955e4a2b408995297627ef704fa3d5267
Author: Michael James Gratton <mike vee net>
Date:   Wed Jan 4 03:32:50 2017 +1100

    Re-enable spell checking in composer.
    
    * src/client/application/geary-config.vala (Configuration): Remove
      spell-check setting, we can just get it from the list of visible
      languages instead. Update the schema.
    
    * src/client/components/client-web-view.vala (WebView::init_web_context):
      Pass in a config object, use that to init WebKit's spell checking on
      the WebContext now that is a global configuration, update it when the
      config changes, update call sites.
    
    * src/client/composer/composer-widget.vala (ComposerWidget): Remove
      WK1-syle spell checking settings prefs.
    
    * src/client/composer/spell-check-popover.vala (SpellCheckPopover): Pass
      a config object in so we don't have to use the global app singleton
      instance.
    
    * src/client/dialogs/preferences-dialog.vala (PreferencesDialog):
      Modernise by converting into a widget template.
    
    * test/client/components/client-web-view-test-case.vala (TestCase):
      Construct a config object as a fixture, use it to init the WebContext
      and make it avalaible to subclasses & update subclasses.
    
    * ui/preferences-dialog.ui: Moved from preferences.dialog, remove spell
      check preference.
