Accessible Tooltip Fix

FIXES

• Accessible tooltips in ordinal summary types and node/edge weren't being passed the same data as was passed on mouse hover
• Custom node and edge marks were sometimes not being honored
• NetworkFrame iterations settings were not being honored

CHORES

• CircleCI status added to readme (thanks @rgbkrk)
• Vendorize element-resize-event and rough so that Semiotic points to NPM versions of each rather than direct to repos.
