[TaskList]:
* format task date on the same node as the title. If space isn't
  there, the date goes on it's own line.
* Truncate output of task status to a maximum of 160 characters to
  fix formating, also the list should only give an overview.
* set list flex to 1, this fixes height and scrolling issues
* Put affected node and status on a own line.

[TaskViewer]
* Only show task status, the exit status is in the log below,
  also some long statuses break this page completely.
