Screenshot from the profiler

Please see the attached screenshot (or the attached snapshot) from self-profiling of IDE start (Build 201202200400).
Tasklist consumes a lot of CPU power by using subproject queries. While user is not blocked from work (scan happens on background), the performance is greatly reduced. On my machine, NB start + scanning (just up-to-date checks!) takes about 30 minutes.

Unnecessary scope checks removed, it speeds up tasklist startup scanning.
