update to d3 v3.1.4 and associated changes
vis fixes + improvements (esp. connection arcs)

- fix bug where connection arcs no longer correctly connect their supposed
  endpoints after resizing the window (caused by not removing the
  stroke-dasharray and stroke-dashoffset attrs when the connection animation
  is complete)
- draw the connection animation starting from the peer and ending with you
  when you're in give mode
- throttle the entire resize handler on resize, not just the redraw function
bump version to 0.0.3 post-tag

should have done this after e6089d1316630
always export "model" to window obj for easier debugging

not just in dev mode
