#42 Alter task properties without the task-details popup.

[mark_k]

When using the task window, I'm constantly futzing around with end dates, priorities and the like.

While %-complete lets you interact with it from the task window, other properties require that you double-click the task and alter the properties there.

It'd be helpful to be able to change a couple task attributes from the task-panel, namely:
- name
- end date
- priority
