Hg 88 in page galleries

this will probably need some fallback to Iscroll or such on Android 2.3

- lazy load component
- lazy load images inside gallery, on scroll
- lazy load elements in gallery, on scroll
  - loads ~3 images on load
  - adds 10 more elements when all images have been loaded/are loading
  - until it reaches end of gallery
- uses thumbnailer to serve thumbs 195x195
- handles click on an image to open correct image in lightbox
- allows for creating different comonents based on type of media being displayed
  - galleries
  - images
  - we need to add videos

There are probably places that can be optimized for performance, but I think this is good for now
Line is pretty long here :loop:
