Feature request : Align `=` and sort options (PR included).

[rquadling]

When putting INI files into a repo, having the entries alphabetically sorted vs being unsorted / unordered, helps a little.

The idea is that things exist in some order in many places in codebases. So when you are unfamiliar with a project and see unordered information ... the question that comes to mind is "What on earth is this order???".

The second thing is purely a cosmetic issue where some projects I've worked on like the = to align. Again, common for some languages.

The PR #190 covers both of these features.

I'm not a JS expert, but the tests I've written provide the consistent output.

I also added tests that covered all combinations of the options (simply as permutations matter sometimes).
