Temporary commit partway through testing
Refactored and added: SVGKSource split into sensible subclasses, and added a subclass to handle loading an SVG directly from a raw, in-memory NSString
Fixed: major bug with [NSCharacterSet SVGWhitespaceCharacterSet]
FIXED: SVGLayeredImageView now defaults to an obvious ugly purple background with error message embedded in the image itself :).
IMPROVED: the demo project now has a cleaner structure for loading the different 'kinds' of sample
Add synthesize statements.
Improved the error message when trying to init an SVGKImageView from an Xcode Interface builder NIB / StoryBoard
Added automatic filename versioning to the library build
Merge branch '1.1.0' into fixing-viewboxes-and-viewports
FIXED: SVGKit now scales images in a standards-compliant way.
NB: it ALSO has some backup techniques - c.f. SVGKImage setScale: - for the cases where the SVG-Spec standard approach WONT work
Updated readme
FIXED: further subtleties with the handling of viewports and viewboxes (this commit is MUCH MORE ROBUST than previous one, it handles more edge-cases, better)
fix linear gradients

transform of the gradients were not taken into account before.
