Provide Editor action key names and menu keys.
Action names are looked up via
abbot.i18n.Strings.get(String) by
prepending the string "actions.".
NOTE: to add a new editor action, define a key for it here and an action
for it in ScriptEditor. Add to the action map in
ScriptEditor.initActions, then (optionally) add it to the menu layout in
ScriptEditor.initMenus.
