Add a way to change default config path

[NightMachinery]

I like to keep the config of some tools that use conf under git, and be able to easily use the backed-up configs in unix systems. The current default config path keeps changing, which doesn't lend itself to this. Ideally, I want everything stored under ~/.sindconf/.

What do you mean by "default config path keeps changing"? The path has never changed. On Linux, it respects XDG_CONFIG_HOME, so you could set that to change the config path.
