Currently when viewing the daemon task for a HarbormasterTargetWorker, all you get is:

Data:
Array
(
    [targetID] => 113109
)

Unfortunately you need DB access to be able to tie the target ID back into a Harbormaster build (to find out what build is currently being run by this task). Instead, a link should be provided to the build (similar to how repository related tasks provide a link to the commit they are working on).
