Add options

Yet another way of setting options (turns out I'm not the only one needing this).

My approach allows for string/symbol shortcuts for option names.

Oh, and no, I'm not going to be adding readme and whatnot; mainly because @qrush ignores pull requests for 3 months so it'd be waste of time.

I'm just posting this in case someone looks in open pull requests and finds this helpful. I'll be using my local `add-options` branch, thankyouverymuch.
