Started making an auto-updating pin info table
Added multitouch dragging for touch interface

Also draggable_test.html, which is just a file to demonstrate and test
the script.
Finished draggable_test.html
get() now works correctly

Also commented out the script reference to D3 in index.html, wasn't
currently using it.
Added draggable slider styles
Merge branch 'dev' of https://github.com/jpzg/YunRobot into dev
Added slider to index.html
Yun now reports errors to client
Slider adapted to control a servo

IT WORKS
FINALLY
Merge remote-tracking branch 'origin/dev'
