Some Animation, Some Improvements

Ok, so now all the dog breeds in the Build-A-Pup right now have animation. More breeds coming at a later date. I've also added a PNG option in the file download and the dog's name will appear in the GIF and the PNG when generated.

It's still very much broken on mobile, which is a bummer. The Unity engine just isn't big on WebGL mobile support, so not sure if I'll be able to get it working.
