Fixed cards to not hard code widths and to use the tag properly
Added a ResponsiveImage component to track image sizes relative to their parent. This consolidates a lot of logic that was starting to be duplicated.
Added an optional maxPercentage property to the assetUtils.getAssetStyle method so that floated images can have a lower max than centered images. This will allow better wrapping of text to keep things readable.
