Title: Added support for zooming through double tap

When the image is in its initial scale, double tapping scales the image by `double-tap-scale` (half of max-scale by default).

A couple of things that would improve the experience immensely but are not implemented:
* Scaling would occur centered on the double tap location
* Scaling would be made with an animation — GestureImageView could even offer this as a method (`zoomTo(float scale)`)

I tried to quickly implement them both with no success, mainly because I wasn't being able to integrate my changes into your structure elegantly. I'll leave them as suggestions.

Cheers!
