changeset 27675:d073f4c70575

histedit: replace @addhisteditaction with @action @action supports verbs, messages, priority, and internal messages should be translated. internal means the action should not be listed. geteditcomment will construct the verbs list based on @actions (prefering priority over non priority, otherwise favoring verbs with short forms over verbs without).
