Merge pull request #13 from rchipman/ws-8-r2

Ws 8 r2
added user authentication with jetty emshare, created crappy way to push canvas. (kind of) made colorpicker work sometimes, reorganized code, added section labels to make tracking easier, fixed canvas modification while adding comment (though only rectangles will still move pins), pushing this to start big rewrite of annotation addition code
fixed up real-time canvas updating and reconciled annotation indices between clients, added an almost functional real-time comment removal feature
fixed broken shape colorizing
