This rewrites the SysConf code for several reasons: * Modernising the SysConf class. The naming was entirely cleaned up. constexpr for constants. * Exposing less stuff in the header. * Probably less efficient parsing and writing logic, but much simpler to understand and use in my opinion. No more hardcoded offsets. No more duplicated code for the initial SYSCONF generation. * More flexibility. It is now possible to add and remove entries, since we rebuild the file. This allows us to stop spamming "section not found" panic alerts; we can now use and insert default entries.
