Issue:
Double application of external icon in menus
If using `config.yaml` to define your menu, and you mark an item as `external`, the menu will show _two_ external icons.  I think that the templates recently starting adding the external icons by default.  We should investigate, and if that is the case, deprecate the `external` flag in the menu configuration.

Pull request description:
Deprecate "external" Keyword in Menu Configuration
This PR fixes #588.

This adds a warning if the "external" keyword is used in a menu item configuration. ~Right now, if someone uses the "external" keyword, the warning will be logged but there will still be two external link icons in the menu item. If it makes more sense to completely remove support for adding the icon ourselves and just log the warning, I can remove the support for adding the icon altogether.~

Edit: I updated this PR to remove all support for the `external` keyword. If someone uses it in a menu configuration, a warning will be logged, but the keyword will be ignored and no external icon image will be generated.
