support for handle link url taps in caption text

[gurhub]

Wonderfull library, thank you for your effort. I found this method and "attributedCaptionForPhotoAtIndex" and try to used. It's very good for using with HTML attributes like . But when I try to use with Click this... it's not able handle open URL. I checked that part of code and see that using UILabel with setAttributedText.

Is there any plan to adding this functionality for library in near future?

I haven't been doing any iOS work lately as I've been pretty busy with some other projects, but I'm open to pull requests.
