All files opened by FileSystem will be closed on spawn/exec to reduce resource usage by new process.
Added permission request to spawn a new app.
Implemented idSysLocal::StartProcess
Sys_SetFatalError prints out a critical slog2 message
Sys_SetLanguageFromSystem now pulls language from OS.
Minor fix to Japanese language code. Had jp when it was ja
Added ability to have BPS update sys_lang, but it would replace any user set language.
Got spawn.h to compile

Wrote partially functioning JSON parser (still in testing)
