Different folder for niv init

[masaeedu]

Might be a little late for this, but I'd prefer it if all my niv stuff went into .niv instead of nix. I was wondering if there's a way to make this configurable and still have everything work?

Here’s something that could work well:

• by default niv looks first in nix/, then in .niv/
• on niv init you can specify —sources-dir

Thoughts ?

@nmattia That seems like a good idea. Regarding sources-dir: would it only support the values nix and .niv, or would it store any value you give it in some config file and then refer to it later?

Maybe another alternative is that niv init works how it always did, but also creates a .nivrc config file in the root of the repo with all the default settings (e.g. "sources-dir": "/nix"). If you pass any flags or environment variables to override those settings, that's what shows up in the .nivrc config file on niv init. All the other commands simply refer to this config file to find the answers to all configurable questions.

Finally, if the .nivrc file is not present all the commands fall back to some default hardcoded niv config that makes the tool work how it used to.
