switched to using node_modules-installed backbone.drowsy
modernized CK.Model
revamped CK.getState and CK.setState
updated to latest version of coffeescript (1.6.2)
compile all ck.smartboard.view.*.coffee files to one ck.smartboard.view.js file
view.coffee files need to be explicitly given as an array, otherwise they're not correctly ordered
CK.setState() now returns the state doc after setting it
forgot to add ck.smartboard.coffee to compile list
don't need d3 libs anymore
change mode now works...
pause/unpause now works on smartboard
CK.getState now correctly sets 'entity' attribute
runState --> model
changed my mind... @model -> @runState in wall view
balloons are rendered again
moved 'Show Word Cloud' button to the right
Revert "don't need d3 libs anymore"

This reverts commit 75b6a1b80c42064d1b9e67b6aafed177851b687f.
backbone.drowsy should not be included in shared/js/libs
trying collision detection using d3
trying with requestAnimationFrame()... not going well
