Show #thr's, but not thr's

[stdedos]

I have an issue with a thread-hungry app, that keeps pushing my user to limits.

With 364 tasks already un-navigatable, I don't think that showing thr's (~2k at the moment) makes any sense. However, maybe the count is not a problem.

I am proposing that Tasks could show (k)thr's count, but without adding their lines in main view.
