Rename vectorImageSize context option to SVGImageSize, which make it clear for SVG spec. (We'll add other vector image format like PDF, so the naming should related to their context)

 To use SVG coder, you should firstly add the `SDImageSVGCoder` to the coders manager. Then you can call the View Category method to start load SVG images.
 
-Because SVG is a [vector image](https://en.wikipedia.org/wiki/Vector_graphics) format, which means it does not have a fixed bitmap size. However, `UIImage` or `CGImage` are all [bitmap image](https://en.wikipedia.org/wiki/Raster_graphics). For `UIImageView`, we will only parse SVG with a fixed image size (from the SVG viewPort information). But we also support you to specify a desired size during image loading using `vectorImageSize` context option.
