Fixed the openflow demo example and some of the related graphs.
Updating graphs to require.js. Pie and sctterplot are still broken.
Demo app fixes
Moe cleanup on the demo example.
More cleanup on graphs
Updating the Bridge example. The Sensor Reading graph is still not working. The sliced table from the server isn't correct. May be an issue with oml_omf. The main problem is most likely in data_sources/sensors-sqlite.rb
