Magic Trailing Commas in isort

[colin99d]

This fixes #1200 by adding magic trailing comma support. Looking forward to your feedback!

[charliermarsh]

Awesome, thank you for this! Will try to review today.

In isort this is configurable with the split_on_trailing_comma option. We should do the same.

[charliermarsh]

Agreed.

I haven't tested but... Awesome!

@charliermarsh it looks like this has some weird behavior when importing with as, even if the feature is disabled. I am not sure why. But I will dig in.

[charliermarsh]

Thank you! Appreciate all the effort and output here :)

I made a few changes (which I think fixed the as handling), but let me know if you have any questions or disagree with any of the choices I made.

I love all of them, thanks for the help!!
