Title: Added support for a border with a given color and width

Hi Oliver

Thanks for putting this popover together. I needed a border for it, so here it is.
The change is straightforward, basically I use the UIBezierPath stroke after all other elements are drawn.

I have created three constants to show the border (default to NO). set the color and set the width.

Here is what it looks like:
