David Robillard 2177f00841 Add AutomationControl::parameter() for terseness.
Future-proof automation track GUI 'extra' XML (<GUI><AutomationChild automation-id="gain"> instead of <GUI><gain> so Parameter.to_string isn't used as an XML node name).
Fix automation track controller bar shown/hidden state.
Fix automation track initial show bug.
