JosJuice b0f9bb9f13 Port some settings to the new config system
Other than the controller settings and JIT debug settings,
these are the only settings which were defined in Java code
but not defined in the new config system in C++. (There are
still a lot of settings that are defined in the new config
system but not yet saveable in the new config system, though.)
