Build a tree of Dropbox conflict dependencies.

As DOT, for feeding graphviz:

$ dropbox_conflicts -output dot ~/Dropbox | neato -T png > conflicts.png && open conflicts.png

or as textual, indented trees, for feeding some other arbitrary tool or just visual inspection:

$ dropbox_conflicts -output trees ~/Dropbox
