New Twitter workflow node, bar chart, and other minor updates

#1

Released a bunch of updates this evening, including:

  1. You can now tweet using workflows. I recommend hooking up a temperature sensor to an Arduino and tweeting about how cold it is in the office when it goes under 65 degrees.
  2. Added a new bar chart dashboard block.
  3. Fixed a bug where you couldn’t drag the line from one workflow node to another workflow node.
  4. Ditched the confusing + buttons everywhere.
  5. Added ability to clear workflow debug logs.
