I like seeing a month long habit consistency graph, but this 
usually overwrites most of the information on each agenda habit 
line unless the window is particularly wide.
The attached patch adds a customizable option to place the graph. 
I'm using it now to place each habit's graph on a new line below 
the habit at `org-habit-graph-column'. It makes this sort of 
customization very simple, e.g.

  (setq org-habit-insert-graph-function
        (lambda (graph)
          (goto-char (point-at-eol))
          (insert "\n")
          (move-to-column org-habit-graph-column t)
          (insert graph)))

Would love to see it included in org-habit.

Thanks,
Nicholas Vollmer
