#114 Displaying completed tasks

[rhizome99]

Currently completed tasks are displayed above open tasks.
Would it be more useful if completed tasks were greyed out or striked-out, as a user would want to focus on on-going tasks.

Furthermore, completed tasks could be displayed below on-going tasks rather than above. Or better still, could they be hidden and require a click to be displayed, as this would make the make viewing the task list a lot less cluttered.
