Add maintainers?

[lukas2]

Hey @ninjinkun, this is a great library but I have noticed that you are not merging pull requests any more.

Perhaps you can add other maintainers who can merge them? :)

I'd love to see this project spun off into a new organization—maybe just called NJKWebViewProgress? The major contributors to the project, basically whomever @ninjinkun nominates, could be given commit rights, and the project could just sort of evolve. Meanwhile, perhaps this particular version could be frozen and all issues and PRs ported over by the new maintainer community for them to do with as they please. That way, there wouldn't be a major shock to anyone using this repo, nor would @ninjinkun have to do any further work beyond creating a new org, choosing a half-dozen people arbitrarily, and saying 'have at.'

It's not an apples-to-apples comparison, but this seems similar to the transition that Jesse Squires helped facilitate for https://github.com/jessesquires/JSQMessagesViewController, which can now be found at https://github.com/MessageKit/MessageKit/
