Fixed list parsing from ConfigIniEnv and adjusted code to match docs.

[apollo13]

Hi there; this is a small patch (with tests) that brings the behavior of ConfigIniEnv in line with other variants. What do you think?

[apollo13]

If you deem this patch backwards compatible I can add a completely backwards compatible one which moves ConfigObj construction into a factory method for instance and keep the original behaviour as default.

I'm kind of pressed for time and I haven't touched Everett in a while so I don't have it loaded into my head. Can you explain what this does specifically?

[apollo13]

Sure; basically it does two things:

• It changes ConfigIniEnv to just load the first found file if passed a list instead of reading all (ie it aligns code with the documented behavior). [ "uses the first one it finds" as documented here ]
• It changes ConfigIniEnv to return plain strings and not let configobj.ConfigObj parse those into lists to align the behavior of ConfigIniEnv with ConfigOSEnv and others which do not change values. This is important in the sense that it is hard to work with it if different configs return different datatypes. If one wants lists from the config, there is already ListOf which achieves that.

If this isn't a class method anymore, then the cls argument should be self.

I'm really sorry this took me so long to look at. This looks super and I really appreciate you working on it!

I had one minor nit. I think I'll land this now and then fix the nit.

Thank you!
