Support '~' in config

[SherLock707]

[Enhancement]

Can you please add support for ~ expansion in config read?

You can check if path string contains ~ , if so os.path.expanduser(path)

While writing back to the config you can override the ~ with actual home path.

Just trying to make if username independent when installing dots on fresh install..

I didn't bother to do it because initially, the user were not supposed to mess with config file as it is updated by the program. But I see that people do it anyway :D So, I'll add the path expansion on occasion.
