Robert Speicher 4a844b73ff Merge branch 'fix-sanitize-svg' into 'master'
Update SVG sanitizer to conform to SVG 1.1

Original SVG sanitizer would strip out necessary elements and attributes.

Use a custom Loofah scrubber since sanitize 2.x transformers are inadequate to handle case-sensitive SVG attributes since they parse documents as HTML instead of XML, which causes all SVG attribute names (e.g. `viewBox`) to be downcased.
