Dependencies between tasks

[quazgar]

it should be possible to have tasks depend on other tasks being completed, to move this app a bit more into a project management direction.

This could be implemented for example by restricting start or due dates on the dates of another task.

Such dependencies would then also imply a sorting order, even if no specific dates are given.

Expected behaviour (details to be discussed)

Allow the user to specify a dependency as follows:

1. Tick a checkbox "Depends on other tasks"
2. From 3 dropdown menus, choose:
   "This tasks cannot {start | end} before other task has been {started | completed}."
3. This should restrict both tasks' date options.
4. Make sure there are no loops in the dependency graph.

I would be interested in at very least having a menu option that lets me specify that task A depends on tasks [B, C, D, ...]. This is probably the one feature from Taskwarrior I miss most after moving to Tasks.
