NB 7.2 HR integration request: #214452: Incorrect claim in editor/hints.html

Description:
http://netbeans.org/bugzilla/show_bug.cgi?id=214452

The help for Tools/Options/Editor/Hints contains a note about an option 
(Show in Tasklist), which does not exist.

Impact assessment: incorrect help message, may lead to a confusion.

Risk assessment: none, only helpset's html is modified
