knotty: improve the UI information

During a build you might end up with bitbake telling you:

	Currently 30 running tasks (2757 of 2757/3476 of 6390)

Which, to me, is really confusing. For one the forward slash separator
and the two numbers immediately on each side of which are likely to be
interpreted as being one unit (i.e. 2757/3476) but they're not.

Add labels, spaces, etc. to help clarify the information bitbake is trying to
convey.

While I agree with what you are trying to achieve, the suggested line 
is very verbose. If my calculations are correct, that leaves only 5-7 
characters for the progress bar in an 80 character window. Here is the 
original line:

Currently 99 running tasks (12345 of 12345/12345 of 12345) 100% |##############|
No currently running tasks (12345 of 12345/12345 of 12345) 100% |##############|

And here is the updated one:

Currently 99 running tasks (setscene:12345/12345 tasks:12345/12345) 100% |#####|
No currently running tasks (setscene:12345/12345 tasks:12345/12345) 100% |#####|

Dropping "Currently ", which is not really needed, would be a start. 
That would also give the "No running tasks ..." variant the same 
formatting:

99 running tasks (setscene:12345/12345 tasks:12345/12345) 100% |###############|
No running tasks (setscene:12345/12345 tasks:12345/12345) 100% |###############|

Personally, I would have preferred the even terser form, since I know 
what those numbers represent:

99 running tasks (12345/12345, 12345/12345) 100% |#############################|
No running tasks (12345/12345, 12345/12345) 100% |#############################|

but that might be too much to ask. And I don't have good alternatives 
to "setscene" and "tasks".

(And if anybody wonders, I love watching those progress bars move 
across the window, which is why I don't want them reduced to only a 
few characters.) ;)
