Two feature updates

There are two minor updates to the site in past few days.

1. Clearer explanation on goal creation form. Especially the label for “progress metrics”. Please note that if you enter anything doesn’t start with a number, the progress will default to be tracked through number of tasks completed.

2. Hide completed tasks on “Tasks” page. Now the completed tasks are not shown on the index page under the “Tasks” menu tab. This is mainly to reduce the clutter if you have more than 2 or 3 goals. However, you can still see those completed tasks on each goal’s dashboard page. Just click on the goal title, you will still see them there.

Also removed the dropdown box for the progress metrics field, as it seems to be useless.
