rose bush: jobs: clickable cycles and task names

A tidy up...

Rose Bush:
* index: Re-order buttons c.f. title text.
* jobs: Create links for cycle and task name in each row for listing
  jobs in the linked cycle or task.
* jobs: Submit fail and signalled jobs should now stand out.
* cycles: Change link style to be the same as job lists.
