Add basic drag and drop functionality

Tasks can be dragged and dropped between buckets.  They cannot be
reordered yet and there's very minimal visual feedback.

Improve the look and feel of drag and drop

A rotating, transparent ghost of a task being dragged is know shown.

A task will  instantly reappear in the bucket it's moved into instead of
disappearing for a second.

Add more drag and drop fluff

Dragged tasks are highlighted, so you can see what task you're dragging

The regular taskview no longer has the redundant "status" JComboBox

When a task is dropped in an invalid area, it will now return back to its
original location.
