Have AmountEdit return an int if is_int, otherwise a Decimal Set the tray tooltip unconditionally. More verbose logging for exchage_rate plugin. Get rate_float from Coindesk as rate can have commas. Plugin tracks windows itself, and doesn't create its own members in the window objects. Clean up the edit handling.
