added Spectrum colorpicker to bower.json, setup in canvas.html and dar.js
moved canvas styling to css file
moved width and height back to canvas DOM definition - setting it in CSS messed with drawing functionality
canvas now floats to the left so user list and color picker are on the right
colorpicker now integrated with canvas stroke color - you can draw in color!
added line item to TODOs
the color a user is drawing in is now send and recived by other users. fixes the issue of everyone seeing black when you are drawing in color
Merge branch 'colors'
