Bug#721647: taskd now released

[Ben Armstrong <synergism@gmail.com>]

See:

http://taskwarrior.org/news/186

  After three years, 400 commits, a false start, a wrong turn, and a
  lengthy beta, Taskserver is finally released.
  ...
  Taskwarrior 2.3.0 (also released today) supports Taskserver.


Also, note that jwilk put taskwarrior 2.3 in experimental recently. So
maybe it's a good time to get taskd uploaded there too? :)

Cheers,
Ben
