Option to use typical platform case conventions?

[chadf]

While on Windows you'll see the directories using capitalization in their app name and author, on unix it has historically used all lowercase names for app dot-files/directories for the most part. Would it be worth adding an option which will make it do-the-right-thing (tm) based on a platform's typical naming convention?

I first thought the opinion parameter could be used to control such a feature, but it just seems to be a boolean. On a side note, would it be worth changing that to a list/tuple (having a boolean compatibility fallback) to allow the end developer to pick an choose which opinionated features to use, rather than an all-or-nothing approach?

If such a feature was added, my thoughts on its implementation:

• If the feature isn't enable, use the app name and author as-is.
• If enabled on unix, do lower() on the value.
• If enabled on Windows and they contain any uppercase characters, use as-is.
• If enabled on Windows and they contain only lowercase, do title() on the value.
• If enabled on macOS, use the same rules as Windows (?)

Also, spaces may be something worth re-writing for the same reasons. Though, I'm not sure what the best handling for that would be.. replacing them with and underscore or dash, or simply removing the spaces altogether.

PR welcome, but this is a feature issue, not a discussion.
