Tweakings to the task title UI-element and the .taskInfo style.

Removed the reduntant "Title: " prefix from task titles, which
brought unneccessary noise to the UI (at least for us with many
tasks).

Also adjusted the css for taskInfo, so that the task title/owner/etc
will line up nicely with the [Task] box.
