Visual feedback on how well the user has ingrained tasks

[rdhammond]

Psychology generally says you need to do something for a month before it becomes a bona fide habit, so we'll use the follow scale for Dailies and Weeklies only:

~1/4 of a month: Cool (blue)
~1/2 of a month: Warm (yellow)
~3/4 of a month: Hot (orange)
one month: Complete (black)

Once complete, we're not going to worry about resetting. If the user falls out of habit, they need to drop the task and re-add it. Mmmmaybe we'll do a manual reset button at some point, idk.

Tracking will be on a simple +1/-1 point scale every time it's checked or missed. "Complete" is when the score for Dailies is 30 or the score for Monthlies is 4. Should be simple enough to track, but we'll need to make model changes to accommodate.
