Fixed the mixing of aircraft coordinates in the details view, by

checking if the ICAO address of the frame and the current item
in the details view match. Slight refactor by placing the decimal
to string conversion function into the string_format module.

Added fix in the scope of issue #365

FrequencyStepView field in TransmitterView class

FrequencyStepView field in TransmitterView class

Update ui_transmitter.hpp

Update credits

Fixed left padding of the decimal part of the numbers.
