A hook event that fires whenever this ApplicationV1 is first rendered to add buttons to its header. Substitute the
"ApplicationV1" in the hook event to target a specific ApplicationV1 type, for example
"getMyApplicationHeaderButtons". Each Application class in the inheritance chain will also fire this hook, i.e.
"getApplicationHeaderButtons" will also fire.
