radius is part of CircleMarker style so should be changeable in using setStyle();

This fixes #1012

[northlandiguana]

Add the following to L.Path._updateStyle:

if (this.options.radius) {
this._radius = this.options.radius;
};

I'm new to GitHub, so I don't know how to do this to the source code on here myself.

Hi northlandiguana, this issue is a pull request containing a fix for it.
In the Files Changed bit you can see what I made of it.
A Path does not have a radius and therefore its code should be kept clean of all things radius.
This needs fixing in CircleMarker, I think.

I took another look at the code and a CircleMarker always has a radius option so the check is superfluous there.

I see where the file update is now. Sorry for being a GitHub virgin :-). Thanks.
