Reorder tasks & Tasks Dependency

[lordlycastle]

It would be useful to reorder tasks so you can keep them in the order you expect to do them in a project.

It would be even cooler if you can say this task depends on that and then it figures out the order; but this is overkill as it will be simpler to just set the task order "rank".

So each task can have a rank value and then we sort on that value.
