Fixed the bug that occurs when a user enters a whiteboard already in
progress. Now when that occurs, the correct whiteboard state is drawn.
Fixed by adding a checkIfDrawingBufferIsNull() to drawDrawingObject() in
Canvas. This method instantiates the DrawingBuffer if its null.
rearranged some stuff in terms of what package they were in
changed ToolbarGUI to become a nested class in CollaboardGUI, I didn't like that it had to have a reference to canvas to work properly
