Update Terminal Name In Env Variable
The console supports truecolor but still reports itself as "xterm-256color" changing it to "xterm-truecolor" would be more accurate and follow suite with common color detection schemes.
env = g_environ_setenv (env, "TERM", "xterm-256color", TRUE);
to
env = g_environ_setenv (env, "TERM", "xterm-truecolor", TRUE);
in kgx-simple-tab.c should do the trick unless I'm misunderstanding things.
