* lisp/org-habit.el: (org-habit-parse-todo) Don't parse more days than needed.
When constructing a consistency graph, org-habit (with this patch) will stop searching for timestamps when the number of matches exceeds the span of time displayed in the graph. This can produce a significant speedup in agenda construction, especially for entries with many logbook entries. Previously, org-habit would parse all logbook timestamps, even if they numbered in the hundreds.
