Core -> Route and Resource Loading: reload component on update

[leandrocp]

When a component is updated it should be reloaded with the following code to apply the changes on the site:

    Beacon.Loader.ComponentModuleLoader.load_components(
      current_site,
      Beacon.Content.list_components(current_site)
    )

Currently there's no way to reload single components, it has to reload all of them at once.
