By coincidence, shortly after the release of the previous update, I received a test report from the Steam team, who had found of that Huenison didn't open automatically the virtual keyboard on their Steam Deck - of course it didn't: I didn't even know that the Steam Deck existed! While trying to address that issue, I also found out and fixed a few other ones.

v1.8 (23.7.2022)
* Added experimental code to have the Steam on-screen keyboard open automatically when text entering is requested (totally untested due to lack of a Steam Deck; chances are it will not work, as the game is completely software-rendered; feedback welcome).
* Reworked assignments of the kind *p++ = ... *p ... (as they are miscompiled by some versions of gcc).
* Fixed (server side) registration for hiscores / hiscores receiving and added SITE.PORT configuration option for future use.
* Improved/updated manual.
