Task list improvement

We had a suggestion from @johnwlong awhile back to improve the task list page by taking into account newlines.  Previously, the task list simply showed the first X characters of the task.  Now, it shows the first X characters of the first line of the task.

This seems to really simplify the task list while giving users the ability to be more specific about what shows up on that task list page.  Let us know what you think!
