- update to version 2.5.9
* TQSL now accepts 'S' (String) and 'C' (Character) specifiers.
* For AMSAT-Oscar 7, TQSL now accepts "AO-07" as well as "AO-7" for
the satellite name.
* ADIF Modes with slashes can now be mapped to an existing mode
(such as "DATA").
* Remove forced background color settings so system settings for
"Dark Mode" work. (Linux only.)
* Correct the languages "Chinese Traditional" and "Chinese Simplified"
