Revert "Work in progress (currently nicely broken) for preserveAspectRatio on SVGImageElement."

This reverts commit 56f4cd3ab903d703d11e6baad83a3178b2867372.
Implemented preserveAspectRatio for images.
Add ImageAspectRatio sample to the demo app.
Added attribution for ImageAspectRatio.svg.
Remove methods since they aren't part of the spec.
Merge branch '2.x' into image-preserve-aspect

* 2.x:
  ADDED: Can load SVG files from NSData sources, with working URL relative links. ADDED: SVG-image tag can point to local or remote SVG files (based on an idea by trilogysci)
  FIXED: removed confusing and incorrect SVGImage define

Resolved conflicts:
	Source/DOM classes/Unported or Partial DOM/SVGImageElement.m
	XCodeProjectData/Demo-iOS/MasterViewController.m
Merge pull request #195 from dgileadi/image-preserve-aspect
